Results are presented from a search for long-lived neutralinos decaying into a photon and an invisible particle, a signature associated with gauge-mediated supersymmetry breaking in supersymmetric models. The analysis is based on a 4.9fb-1 sample of proton-proton collisions at s=7TeV, collected with the CMS detector at the LHC. The missing transverse energy and the time of arrival of the photon at the electromagnetic calorimeter are used to search for an excess of events over the expected background. No significant excess is observed, and lower limits at the 95% confidence level are obtained on the mass of the lightest neutralino, m>220GeV (for c?6000mm (for m<150GeV). © 2013 CERN ; California Earthquake Authority Serbia Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro Fuel Cell Technologies Program, FCT Joint Institute for Nuclear Research, JINR: Ukraine Bundesministerium für Wissenschaft und Forschung, BMWF Marketing Science Institute Pakistan Atomic Energy Commission: Pakistan Consejo Nacional de Ciencia y Tecnología National Science and Technology Development Agency: Thailand Institute for Research in Fundamental Sciences Hispanics in Philanthropy California Department of Fish and Game Secretaría de Estado de Investigación, Desarrollo e Innovación National Research Foundation Centers for Medicare and Medicaid Services U.S. Department of Energy Academy of Finland Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Türkiye Atom Enerjisi Kurumu Ministerio de Educación y Cultura Taipei Research Promotion Foundation: Cyprus, SF0690030s09 National Science Foundation Science and Technology Facilities Council Human Growth Foundation Croatia Austrian Science Fund Fundação de Amparo à Pesquisa do Estado de São Paulo Secretaría de Educación Pública Western Carolina University Fonds De La Recherche Scientifique - FNRS National Academy of Sciences of Ukraine National Natural Science Foundation of China Bundesministerium für Bildung und Forschung Instituto Nazionale di Fisica Nucleare Hungarian Scientific Research Fund Department of Atomic Energy, Government of India Rochester Academy of Science Department of Science and Technology, Government of Rajasthan Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq ?????????? ???? ??????????????? ????????????

Measurements of event shapes and azimuthal correlations are presented for events where a Z boson is produced in association with jets in proton-proton collisions. The data collected with the CMS detector at the CERN LHC at s=7 TeV correspond to an integrated luminosity of 5.0 fb-1. The analysis provides a test of predictions from perturbative QCD for a process that represents a substantial background to many physics channels. Results are presented as a function of jet multiplicity, for inclusive Z boson production and for Z bosons with transverse momenta greater than 150 GeV, and compared to predictions from Monte Carlo event generators that include leading-order multiparton matrix-element (with up to four hard partons in the final state) and next-to-leading-order simulations of Z+1-jet events. The experimental results are corrected for detector effects, and can be compared directly with other QCD models. © 2013 CERN ; California Earthquake Authority Serbia Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro Fuel Cell Technologies Program, FCT Joint Institute for Nuclear Research, JINR: Ukraine Marketing Science Institute Bundesministerium für Wissenschaft und Forschung, BMWF Pakistan Atomic Energy Commission: Pakistan Consejo Nacional de Ciencia y Tecnología National Science and Technology Development Agency: Thailand Institute for Research in Fundamental Sciences Hispanics in Philanthropy California Department of Fish and Game National Research Foundation Secretaría de Estado de Investigación, Desarrollo e Innovación Centers for Medicare and Medicaid Services U.S. Department of Energy Academy of Finland Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Türkiye Atom Enerjisi Kurumu Ministerio de Educación y Cultura Taipei Research Promotion Foundation: Cyprus, SF0690030s09 National Science Foundation Science and Technology Facilities Council Human Growth Foundation Croatia Austrian Science Fund Fundação de Amparo à Pesquisa do Estado de São Paulo Secretaría de Educación Pública Western Carolina University Fonds De La Recherche Scientifique - FNRS National Academy of Sciences of Ukraine Bundesministerium für Bildung und Forschung National Natural Science Foundation of China Instituto Nazionale di Fisica Nucleare Hungarian Scientific Research Fund Department of Atomic Energy, Government of India Rochester Academy of Science Department of Science and Technology, Government of Rajasthan Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq ?????????? ???? ??????????????? ????????????

A measurement is presented of the inelastic proton-proton cross section at a centre-of-mass energy of ?s=7 TeV. Using the CMS detector at the LHC, the inelastic cross section is measured through two independent methods based on information from (i) forward calorimetry (for pseudorapidity 3200 MeV/c. The measurements cover a large fraction of the inelastic cross section for particle production over about nine units of pseudorapidity and down to small transverse momenta. The results are compared with those of other experiments, and with models used to describe high-energy hadronic interactions. © 2013 CERN. ; California Earthquake Authority Serbia Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro Fuel Cell Technologies Program, FCT Joint Institute for Nuclear Research, JINR: Ukraine Bundesministerium für Wissenschaft und Forschung, BMWF Marketing Science Institute Pakistan Atomic Energy Commission: Pakistan Consejo Nacional de Ciencia y Tecnología Institute for Research in Fundamental Sciences National Electronics and Computer Technology Center: Thailand Hispanics in Philanthropy California Department of Fish and Game Secretaría de Estado de Investigación, Desarrollo e Innovación National Research Foundation Canadian Mathematical Society U.S. Department of Energy Academy of Finland Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Ministerio de Educación y Cultura Türkiye Atom Enerjisi Kurumu Taipei Research Promotion Foundation: Cyprus, SF0690030s09 National Science Foundation Science and Technology Facilities Council Human Growth Foundation Croatia Austrian Science Fund Fundação de Amparo à Pesquisa do Estado de São Paulo Secretaría de Educación Pública Western Carolina University Fonds De La Recherche Scientifique - FNRS National Academy of Sciences of Ukraine Bundesministerium für Bildung und Forschung National Natural Science Foundation of China Instituto Nazionale di Fisica Nucleare Hungarian Scientific Research Fund Department of Atomic Energy, Government of India Rochester Academy of Science Department of Science and Technology, Government of Rajasthan Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq ?????????? ???? ??????????????? ????????????

The W+W- and ZZ production cross sections are measured in proton-proton collisions at s=8TeV with the CMS experiment at the LHC in data samples corresponding to an integrated luminosity of up to 5.3fb-1. The measurements are performed in the leptonic decay modes W+W-›l'?l¨? and ZZ›2l2l', where l=e,µ and l'(l¨)=e,µ,?. The measured cross sections ?(pp›W+W-)=69.9±2.8(stat.)±5.6(syst.)±3.1(lum.) pb and ?(pp›ZZ)=8.4±1.0(stat.)±0.7(syst.)±0.4(lum.) pb, for both Z bosons produced in the mass region 60

An updated search for heavy narrow resonances decaying to muon or electron pairs using the CMS detector is presented. Data samples from pp collisions at s=7 TeV and 8 TeV at the LHC, with integrated luminosities of up to 5.3 and 4.1 fb-1, respectively, are combined. No evidence for a heavy narrow resonance is observed. The analysis of the combined data sets excludes, at 95% confidence level, a Sequential Standard Model ZSSM ' resonance lighter than 2590 GeV, a superstring-inspired Z? ' lighter than 2260 GeV, and Kaluza–Klein gravitons lighter than 2390 (2030) GeV, assuming that the coupling parameter k/M¯Pl is 0.10 (0.05). These are the most stringent limits to date. © 2012 CERN ; California Earthquake Authority Serbia Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro Fuel Cell Technologies Program Joint Institute for Nuclear Research: Ukraine Bundesministerium für Wissenschaft und Forschung Marketing Science Institute Pakistan Atomic Energy Commission: Pakistan Consejo Nacional de Ciencia y Tecnología National Science and Technology Development Agency: Thailand Institute for Research in Fundamental Sciences Hispanics in Philanthropy California Department of Fish and Game Secretaría de Estado de Investigación, Desarrollo e Innovación National Research Foundation Centers for Medicare and Medicaid Services U.S. Department of Energy Academy of Finland Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Ministerio de Educación y Cultura Türkiye Atom Enerjisi Kurumu Taipei Research Promotion Foundation: Cyprus, SF0690030s09 National Sleep Foundation Science and Technology Facilities Council Human Growth Foundation Croatia Austrian Science Fund Fundação de Amparo à Pesquisa do Estado de São Paulo Secretaría de Educación Pública Western Carolina University Fonds De La Recherche Scientifique - FNRS National Academy of Sciences of Ukraine Bundesministerium für Bildung und Forschung National Natural Science Foundation of China Instituto Nazionale di Fisica Nucleare Hungarian Scientific Research Fund Department of Atomic Energy, Government of India Rochester Academy of Science Department of Science and Technology, Government of Rajasthan Conselho Nacional de Desenvolvimento Científico e Tecnológico ?????????? ???? ??????????????? ????????????

A measurement of W+W- production in pp collisions at s=7 TeV and a search for the Higgs boson are reported. The W+W- candidates are selected in events with two leptons, either electrons or muons. The measurement is performed using LHC data recorded with the CMS detector, corresponding to an integrated luminosity of 36 pb-1. The pp › W+W- cross section is measured to be 41.1±15.3(stat)±5.8(syst)±4.5(lumi)pb, consistent with the standard model prediction. Limits on WW? and WWZ anomalous triple gauge couplings are set. The search for the standard model Higgs boson in the W+W- decay mode does not reveal any evidence of excess above backgrounds. Limits are set on the production of the Higgs boson in the context of the standard model and in the presence of a sequential fourth family of fermions with high masses. In the latter context, a Higgs boson with mass between 144 and 207 GeV/c2 is ruled out at 95% confidence level. © 2011 CERN ; California Earthquake Authority Serbia Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro Fuel Cell Technologies Program Joint Institute for Nuclear Research Pakistan Atomic Energy Commission: Pakistan Consejo Nacional de Ciencia y Tecnología Institute for Research in Fundamental Sciences Foundation for Promotion of Material Science and Technology of Japan Hispanics in Philanthropy Fonds pour la Formation à la Recherche dans l'Industrie et dans l'Agriculture California Department of Fish and Game National Research Foundation Canadian Mathematical Society A.G.

Auf das Problem der Überleitung bestehender Rechtspositionen vom alten in das neue (geänderte) Recht antwortet die Rechtsprechung seit jeher mit dem verfassungsrechtlichen Erfordernis angemessener Übergangsfristen, ohne dass "Angemessenheit" - isoliert betrachtet - ausreichend bestimmt ist. Der Autor präsentiert eine detaillierte und kritische Auseinandersetzung mit der Rechtsprechung und stellt einen ausführlichen Katalog von Kriterien auf, an denen sich notwendige Übergangsfristen messen lassen müssen. Dadurch wird ein Weg aufgezeigt, auf bestehende Positionen bei Änderungsbedarf angemessen Rücksicht zu nehmen sowie die bestehende Rechtsunsicherheit und das Prozessrisiko zu verringern. Das Werk richtet sich primär an Verfassungsjuristen und die einschlägige Praxis

A search for supersymmetry with R-parity conservation in proton–proton collisions at a centre-of-mass energy of 7 TeV is presented. The data correspond to an integrated luminosity of 35 pb -1 collected by the CMS experiment at the LHC. The search is performed in events with jets and significant missing transverse energy, characteristic of the decays of heavy, pair-produced squarks and gluinos. The primary background, from standard model multijet production, is reduced by several orders of magnitude to a negligible level by the application of a set of robust kinematic requirements. With this selection, the data are consistent with the standard model backgrounds, namely tt¯, W + jet and Z + jet production, which are estimated from data control samples. Limits are set on the parameters of the constrained minimal supersymmetric extension of the standard model. These limits extend those set previously by experiments at the Tevatron and LEP colliders. © 2011 CMS Collaboration ; California Earthquake Authority Serbia Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro Fuel Cell Technologies Program, FCT Joint Institute for Nuclear Research, JINR Pakistan Atomic Energy Commission: Pakistan Consejo Nacional de Ciencia y Tecnología Institute for Research in Fundamental Sciences Foundation for Promotion of Material Science and Technology of Japan Hispanics in Philanthropy California Department of Fish and Game National Research Foundation Canadian Mathematical Society U.S. Department of Energy Academy of Finland Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Türkiye Atom Enerjisi Kurumu NSC, Taipei Research Promotion Foundation: Cyprus National Science Foundation Science and Technology Facilities Council Human Growth Foundation Croatia Fundação de Amparo à Pesquisa do Estado de São Paulo Secretaría de Educación Pública Western Carolina University Fonds De La Recherche Scientifique - FNRS National Natural Science Foundation of China Bundesministerium für Bildung und Forschung Ministerio de Ciencia e Innovación, MICINN Instituto Nazionale di Fisica Nucleare Hungarian Scientific Research Fund Department of Atomic Energy, Government of India Department of Science and Technology, Government of Rajasthan Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq Canadian Anesthesiologists' Society Departamento Administrativo de Ciencia, Tecnología e Innovación, COLCIENCIAS Nemzeti Kutatási és Technológiai Hivatal, NKTH: Hungary CERN General Secretariat for Research and Technology, GSRT Fonds Wetenschappelijk Onderzoek Santa Fe Institute Ministry of Education and Science Louisiana Academy of Sciences ; We thank L.
