WOS:000452960100003 ; PubMed:30608761 ; Three of the most significant measured deviations from standard model predictions, the enhanced decay rate for B -> D-(*())tau nu, hints of lepton universality violation in B -> K-(*())ll decays, and the anomalous magnetic moment of the muon, can be explained by the existence of leptoquarks (LQs) with large couplings to third-generation quarks and masses at the TeV scale. The existence of these states can be probed at the LHC in high energy proton-proton collisions. A novel search is presented for pair production of LQs coupled to a top quark and a muon using data at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), recorded by the CMS experiment. No deviation from the standard model prediction has been observed and scalar LQs decaying exclusively into t mu are excluded up to masses of 1420 GeV. The results of this search are combined with those from previous searches for LQ decays into t tau and b nu, which excluded scalar LQs below masses of 900 and 1080 GeV. Vector LQs are excluded up to masses of 1190 GeV for all possible combinations of branching fractions to t mu, t tau and b nu. With this analysis, all relevant couplings of LQs with an electric charge of -1/3 to third-generation quarks are probed for the first time. ; BMWFW (Austria); FWF (Austria)Austrian Science Fund (FWF); FNRS (Belgium)Fonds de la Recherche Scientifique - FNRS; FWO (Belgium)FWO; CNPq (Brazil)National Council for Scientific and Technological Development (CNPq); CAPES (Brazil)CAPES; FAPERJ (Brazil)Carlos Chagas Filho Foundation for Research Support of the State of Rio de Janeiro (FAPERJ); FAPESP (Brazil)Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP); MES (Bulgaria); CERN; CAS (China)Chinese Academy of Sciences; MoST (China)Ministry of Science and Technology, China; NSFC (China)National Natural Science Foundation of China; COLCIENCIAS (Colombia)Departamento Administrativo de Ciencia, Tecnologia e Innovacion Colciencias; MSES (Croatia); CSF (Croatia); RPF (Cyprus); SENESCYT (Ecuador); MoER (Estonia); ERC IUT (Estonia); ERDF (Estonia)European Union (EU); Academy of Finland (Finland)Academy of Finland; MEC (Finland)Ministry of Education and Science, Spain; HIP (Finland); CEA (France)French Atomic Energy Commission; CNRS/IN2P3 (France)Centre National de la Recherche Scientifique (CNRS); BMBF (Germany)Federal Ministry of Education & Research (BMBF); DFG (Germany)German Research Foundation (DFG); HGF (Germany); GSRT (Greece)Greek Ministry of Development-GSRT; OTKA (Hungary)Orszagos Tudomanyos Kutatasi Alapprogramok (OTKA); NIH (Hungary)United States Department of Health & Human ServicesNational Institutes of Health (NIH) - USA; DAE (India)Department of Atomic Energy (DAE); DST (India)Department of Science & Technology (India); IPM (Iran); SFI (Ireland)Science Foundation Ireland; INFN (Italy)Istituto Nazionale di Fisica Nucleare; MSIP (Republic of Korea); NRF (Republic of Korea); LAS (Lithuania); MOE (Malaysia); UM (Malaysia); BUAP (Mexico); CINVESTAV (Mexico); CONACYT (Mexico)Consejo Nacional de Ciencia y Tecnologia (CONACyT); LNS (Mexico); SEP (Mexico); UASLP-FAI (Mexico); MBIE (New Zealand); PAEC (Pakistan); MSHE (Poland); NSC (Poland); FCT (Portugal)Fundacao para a Ciencia e a Tecnologia (FCT); JINR (Dubna); MON (Russia); RosAtom (Russia); RAS (Russia)Russian Academy of Sciences; RFBR (Russia)Russian Foundation for Basic Research (RFBR); RAEP (Russia); MESTD (Serbia); SEIDI (Spain); CPAN (Spain); PCTI (Spain); FEDER (Spain)European Union (EU); MST (Taipei); ThEPCenter (Thailand); IPST (Thailand); STAR (Thailand); NSTDA (Thailand); TUBITAK (Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK); TAEK (Turkey)Ministry of Energy & Natural Resources - Turkey; NASU (Ukraine); SFFR (Ukraine)State Fund for Fundamental Research (SFFR); STFC (United Kingdom)Science & Technology Facilities Council (STFC); DOE (USA)United States Department of Energy (DOE); NSF (USA)National Science Foundation (NSF) ; We congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort.

A measurement of the ratio of the branching fractions of the Bs0 meson to J/?f0(980) and to J/??(1020) is presented. The J/?, f0(980), and ?(1020) are observed through their decays to ?+?-, ?+?-, and K+K-, respectively. The f0 and the ? are identified by requiring |M?+?--974 MeV|>50 MeV and |MK+K--1020 MeV|>10 MeV. The analysis is based on a data sample of pp collisions at a centre-of-mass energy of 7 TeV, collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 5.3 fb-1. The measured ratio is B(Bs0?J/?f0)B(f0??+?-)/B(Bs0?J/??)B(??K+K-) = 0.140±0.008(stat) ± 0.023(syst), where the first uncertainty is statistical and the second is systematic ; Science and Technology Facilities Council: CMS Science and Technology Facilities Council: GRIDPP Science and Technology Facilities Council: PP/E000479/1 Science and Technology Facilities Council: PP/E002803/1 Science and Technology Facilities Council: ST/H000925/1 Science and Technology Facilities Council: ST/H000925/2 Science and Technology Facilities Council: ST/I000305/1 Science and Technology Facilities Council: ST/I003622/1 Science and Technology Facilities Council: ST/J004871/1 Science and Technology Facilities Council: ST/J005479/1 Science and Technology Facilities Council: ST/K001256/1 Science and Technology Facilities Council: ST/K001531/1 Science and Technology Facilities Council: ST/K001639/1 Science and Technology Facilities Council: ST/K003542/1 Science and Technology Facilities Council: ST/L005603/1 Science and Technology Facilities Council: ST/M002020/1 Science and Technology Facilities Council: ST/M004775/1 Science and Technology Facilities Council: ST/N000242/1 Science and Technology Facilities Council: ST/N000250/1 Science and Technology Facilities Council: ST/N001273/1 ; We congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort.

Results are presented from a search for new physics in final states containing a photon and missing transverse momentum. The data correspond to an integrated luminosity of 19.6 fb?1 collected in proton–proton collisions at s=8 TeV with the CMS experiment at the LHC. No deviation from the standard model predictions is observed for these final states. New, improved limits are set on dark matter production and on parameters of models with large extra dimensions. In particular, the first limits from the LHC on branon production are found and significantly extend previous limits from LEP and the Tevatron. An upper limit of 14.0 fb on the cross section is set at the 95% confidence level for events with a monophoton final state with photon transverse momentum greater than 145 GeV and missing transverse momentum greater than 140 GeV ; California Earthquake Authority Fonds pour la Formation à la Recherche dans l'Industrie et dans l'Agriculture European Regional Development Fund State Fund for Fundamental Research of Ukraine: Ukraine Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro CS Fund: Croatia Fuel Cell Technologies Program Joint Institute for Nuclear Research Ministry of Education - Singapore Pakistan Atomic Energy Commission: Pakistan Consejo Nacional de Ciencia y Tecnología National Science and Technology Development Agency: Thailand Ministry for Business Innovation and Employment Institute for Research in Fundamental Sciences Fundacja na rzecz Nauki Polskiej Foundation for Promotion of Material Science and Technology of Japan: Taipei Hispanics in Philanthropy Korea Research Council for Industrial Science and Technology Compagnia di San Paolo California Department of Fish and Game National Research Foundation Qatar National Research Fund Secretaría de Estado de Investigación, Desarrollo e Innovación Canadian Mathematical Society A.G.

The first study of W boson production in pPb collisions is presented, for bosons decaying to a muon or electron, and a neutrino. The measurements are based on a data sample corresponding to an integrated luminosity of 34.6 nb?1 at a nucleon–nucleon centre-of-mass energy of sNN=5.02 TeV, collected by the CMS experiment. The W boson differential cross sections, lepton charge asymmetry, and forward–backward asymmetries are measured for leptons of transverse momentum exceeding 25 GeV/c, and as a function of the lepton pseudorapidity in the |?lab|>2.4 range. Deviations from the expectations based on currently available parton distribution functions are observed, showing the need for including W boson data in nuclear parton distribution global fits ; California Earthquake Authority European Regional Development Fund Joint Institute for Nuclear Research Pakistan Atomic Energy Commission: Pakistan National Science and Technology Development Agency: Thailand Fundacja na rzecz Nauki Polskiej Korea Research Council for Industrial Science and Technology Hispanics in Philanthropy Compagnia di San Paolo California Department of Fish and Game Qatar National Research Fund Secretaría de Estado de Investigación, Desarrollo e Innovación National Research Foundation Ministry of Science ICT and Future Planning Canadian Mathematical Society A.G.

We present a measurement of the Z boson differential cross section in rapidity and transverse momentum using a data sample of pp collision events at a centre-of-mass energy s=8 TeV, corresponding to an integrated luminosity of 19.7 fb?1. The Z boson is identified via its decay to a pair of muons. The measurement provides a precision test of quantum chromodynamics over a large region of phase space. In addition, due to the small experimental uncertainties in the measurement the data has the potential to constrain the gluon parton distribution function in the kinematic regime important for Higgs boson production via gluon fusion. The results agree with the next-to-next-to-leading-order predictions computed with the FEWZ program.

A model-independent search for a narrow resonance produced in proton-proton collisions at s=8 TeV and decaying to a pair of 125 GeV Higgs bosons that in turn each decays into a bottom quark-antiquark pair is performed by the CMS experiment at the LHC. The analyzed data correspond to an integrated luminosity of 17.9 fb-1. No evidence for a signal is observed. Upper limits at a 95% confidence level on the production cross section for such a resonance, in the mass range from 270 to 1100 GeV, are reported.

Abstract: A search for pair production of neutral color-octet weak-triplet scalar particles (?0) is performed in processes where one ?0 decays to a pair of b quark jets and the other to a Z boson plus a jet, with the Z boson decaying to a pair of electrons or muons. The search is performed with data collected by the CMS experiment at the CERN LHC corresponding to an integrated luminosity of 19.7 fb?1 of proton-proton collisions at ?s = 8TeV. The number of observed events is found to be in agreement with the standard model predictions. The 95% confidence level upper limit on the product of the cross section and branching fraction is obtained as a function of the ?0 mass. The 95% confidence level lower bounds on the ?0 mass are found to be 623 and 426 GeV, for two different octo-triplet theoretical scenarios. These are the first direct experimental bounds on particles predicted by the octo-triplet model ; Bundesministerium für Bildung und Forschung Biomedical Engineering Society Bundesministerium für Wissenschaft, Forschung und Wirtschaft Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Canadian Anesthesiologists' Society Commissariat à l'Énergie Atomique et aux Énergies Alternatives Conselho Nacional de Desenvolvimento Científico e Tecnológico Centre National de la Recherche Scientifique Consejo Nacional de Ciencia y Tecnología Children's Specialists Foundation Department of Atomic Energy, Government of India Deutsche Forschungsgemeinschaft U.S. Department of Energy Department of Science and Technology, Ministry of Science and Technology Fonds De La Recherche Scientifique - FNRS Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro Fundação de Amparo à Pesquisa do Estado de São Paulo Fundação para a Ciência e a Tecnologia Austrian Science Fund Fonds Wetenschappelijk Onderzoek General Secretariat for Research and Technology Istituto Nazionale di Fisica Nucleare Institute for Research in Fundamental Sciences Ministry of Business, Innovation and Employment Ministry of Science ICT and Future Planning National Academy of Sciences of Ukraine National Research Foundation of Korea National Science Foundation National Natural Science Foundation of China National Science and Technology Development Agency Országos Tudományos Kutatási Alapprogramok Russian Academy of Sciences Russian Foundation for Basic Research Research Promotion Foundation Secretaría de Estado de Investigación, Desarrollo e Innovación Science Foundation Ireland Science and Technology Facilities Council

Differential cross sections as a function of transverse momentum pT are presented for the production of ?(nS) (n = 1, 2, 3) states decaying into a pair of muons. Data corresponding to an integrated luminosity of 4.9fb?1 in pp collisions at s=7TeV were collected with the CMS detector at the LHC. The analysis selects events with dimuon rapidity |y| >1.2 and dimuon transverse momentum in the range 10 >pT >100GeV. The measurements show a transition from an exponential to a power-law behavior at pT?20GeV for the three ? states. Above that transition, the ?(3S) spectrum is significantly harder than that of the ?(1S). The ratios of the ?(3S) and ?(2S) differential cross sections to the ?(1S) cross section show a rise as pT increases at low pT, then become flatter at higher pT ; California Earthquake Authority European Regional Development Fund Fonds pour la Formation à la Recherche dans l'Industrie et dans l'Agriculture State Fund for Fundamental Research of Ukraine: Ukraine Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro CS Fund: Croatia Fuel Cell Technologies Program Joint Institute for Nuclear Research Ministry of Education - Singapore Pakistan Atomic Energy Commission: Pakistan Consejo Nacional de Ciencia y Tecnología National Science and Technology Development Agency: Thailand Ministry for Business Innovation and Employment Institute for Research in Fundamental Sciences Ministry of Science and Technology Foundation for Promotion of Material Science and Technology of Japan: Taipei Hispanics in Philanthropy Korea Research Council for Industrial Science and Technology California Department of Fish and Game Compagnia di San Paolo Secretaría de Estado de Investigación, Desarrollo e Innovación National Research Foundation Qatar National Research Fund Ministry of Science ICT and Future Planning Canadian Mathematical Society A.G.

The first direct search for lepton-flavour-violating decays of the recently discovered Higgs boson (H) is described. The search is performed in the H???e and H???h channels, where ?e and ?h are tau leptons reconstructed in the electronic and hadronic decay channels, respectively. The data sample used in this search was collected in pp collisions at a centre-of-mass energy of s=8 TeV with the CMS experiment at the CERN LHC and corresponds to an integrated luminosity of 19.7 fb?1. The sensitivity of the search is an order of magnitude better than the existing indirect limits. A slight excess of signal events with a significance of 2.4 standard deviations is observed. The p-value of this excess at MH=125 GeV is 0.010. The best fit branching fraction is B(H???)=(0.84?0.37 +0.39)%. A constraint on the branching fraction, B(H???)>1.51% at 95% confidence level is set. This limit is subsequently used to constrain the ?–? Yukawa couplings to be less than 3.6×10?3 ; California Earthquake Authority Fonds pour la Formation à la Recherche dans l'Industrie et dans l'Agriculture Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro State Fund for Fundamental Research of Ukraine: Ukraine CS Fund: Croatia Fuel Cell Technologies Program Joint Institute for Nuclear Research Ministry of Education - Singapore Pakistan Atomic Energy Commission: Pakistan Consejo Nacional de Ciencia y Tecnología National Science and Technology Development Agency: Thailand Ministry for Business Innovation and Employment Institute for Research in Fundamental Sciences Fundacja na rzecz Nauki Polskiej Foundation for Promotion of Material Science and Technology of Japan: Taipei Hispanics in Philanthropy Korea Research Council for Industrial Science and Technology Compagnia di San Paolo California Department of Fish and Game National Research Foundation Secretaría de Estado de Investigación, Desarrollo e Innovación Qatar National Research Fund Ministry of Science ICT and Future Planning Canadian Mathematical Society A.G.

A search for a narrow, high-mass resonance decaying into Z and Higgs (H) bosons is presented. The final state studied consists of a merged jet pair and a ? pair resulting from the decays of Z and H bosons, respectively. The analysis is based on a data sample of proton–proton collisions at a center-of-mass energy of 8 TeV, collected with the CMS experiment in 2012, and corresponding to an integrated luminosity of 19.7 fb?1. In the resonance mass range of interest, which extends from 0.8 to 2.5 TeV, the Z and H bosons are produced with large momenta, which implies that the final products of the two quarks or the two ? leptons must be detected within a small angular interval. From a combination of all possible decay modes of the ? leptons, production cross sections in a range between 0.9 and 27.8 fb are excluded at 95% confidence level, depending on the resonance mass ; California Earthquake Authority European Regional Development Fund Joint Institute for Nuclear Research Pakistan Atomic Energy Commission: Pakistan National Science and Technology Development Agency: Thailand Ministry of Science and Technology Korea Research Council for Industrial Science and Technology Hispanics in Philanthropy California Department of Fish and Game Compagnia di San Paolo Qatar National Research Fund National Research Foundation Secretaría de Estado de Investigación, Desarrollo e Innovación Ministry of Science ICT and Future Planning Canadian Mathematical Society A.G.
