Major contributors of computing resources are listed in ref. [121]. ; A search for charged Higgs bosons decaying into (WW +/-)-W-+/- or W(+/-)Z bosons is performed, involving experimental signatures with two leptons of the same charge, or three or four leptons with a variety of charge combinations, missing transverse momentum and jets. A data sample of proton-proton collisions at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider between 2015 and 2018 is used. The data correspond to a total integrated luminosity of 139 fb(-1). The search is guided by a type-II seesaw model that extends the scalar sector of the Standard Model with a scalar triplet, leading to a phenomenology that includes doubly and singly charged Higgs bosons. Two scenarios are explored, corresponding to the pair production of doubly charged H-+/-+/- bosons, or the associated production of a doubly charged H-+/-+/- boson and a singly charged H-+/- boson. No significant deviations from the Standard Model predictions are observed. H-+/-+/- bosons are excluded at 95% confidence level up to 350 GeV and 230 GeV for the pair and associated production modes, respectively. ; ANPCyT, Argentina ; YerPhI, Armenia ; ARC, Australia ; BMWFW and FWF, Austria ; ANAS, Azerbaijan ; SSTC, Belarus ; CNPq and FAPESP, Brazil ; NSERC, NRC and CFI, Canada ; CERN ; ANID, Chile ; CAS, MOST and NSFC, China ; COLCIENCIAS, Colombia ; MSMT CR, MPO CR and VSC CR, Czech Republic ; DNRF and DNSRC, Denmark ; IN2P3-CNRS and CEA-DRF/IRFU, France ; SRNSFG, Georgia ; BMBF, HGF and MPG, Germany ; GSRT, Greece ; RGC and Hong Kong SAR, China ; ISF and Benoziyo Center, Israel ; INFN, Italy ; MEXT and JSPS, Japan ; CNRST, Morocco ; NWO, Netherlands ; RCN, Norway ; MNiSW and NCN, Poland ; FCT, Portugal ; MNE/IFA, Romania ; JINR ; MES of Russia and NRC KI, Russian Federation ; MESTD, Serbia ; MSSR, Slovakia ; ARRS and MIZŠ, Slovenia ; DST/NRF, South Africa ; MICINN, Spain ; SRC and Wallenberg Foundation, Sweden ; SERI, SNSF and Cantons of Bern and Geneva, Switzerland ; MOST, Taiwan ; TAEK, Turkey ; STFC, U.K. ; DOE and NSF, U.S.A. ; BCKDF, CANARIE, Compute Canada, CRC and IVADO, Canada ; Beijing Municipal Science & Technology Commission, China ; COST, ERC, ERDF, Horizon 2020 and Marie Sk`odowska-Curie Actions, European Union ; Investissements d'Avenir Labex, Investissements d'Avenir Idex and ANR, France ; DFG and AvH Foundation, Germany ; Herakleitos, Thales and Aristeia programmes co-financed by EU-ESF and the Greek NSRF, Greece ; BSF-NSF and GIF, Israel ; La Caixa Banking Foundation, CERCA Programme Generalitat de Catalunya and PROMETEO and GenT Programmes Generalitat Valenciana, Spain ; Göran Gustafssons Stiftelse, Sweden ; The Royal Society and Leverhulme Trust, U.K
