The search uses a proton-proton collision data sample at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 139 fb$^{-1}$ recorded by the ATLAS detector during Run 2 of the Large Hadron Collider. This analysis focuses on same-charge leptonic decays, $H^{\\pm \\pm} \\rightarrow \\ell^{\\pm} \\ell^{\\prime \\pm}$ where $\\ell, \\ell^\\prime=e, \\mu, \\tau$, in two-, three-, and four-lepton channels, but only considers final states which include electrons or muons. No evidence of a signal is observed. Corresponding limits on the production cross-section and consequently a lower limit on $m(H^{\\pm \\pm})$ are derived at 95% confidence level. Assuming that the branching ratios to each of the possible leptonic final states are equal, $\\mathcal{B}(H^{\\pm \\pm} \\rightarrow e^\\pm e^\\pm) = \\mathcal{B}(H^{\\pm \\pm} \\rightarrow e^\\pm \\mu^\\pm) = \\mathcal{B}(H^{\\pm \\pm} \\rightarrow \\mu^\\pm \\mu^\\pm) = \\mathcal{B}(H^{\\pm \\pm} \\rightarrow e^\\pm \\tau^\\pm) = \\mathcal{B}(H^{\\pm \\pm} \\rightarrow \\mu^\\pm \\tau^\\pm) = \\mathcal{B}(H^{\\pm \\pm} \\rightarrow \\tau^\\pm \\tau^\\pm) = 1/6$, the observed lower limit on the mass of a doubly charged Higgs boson is 1080 GeV within the left-right symmetric type-II seesaw model, which is an improvement over previous limits. Additionally, a lower limit of $m(H^{\\pm \\pm})$ = 900 GeV is obtained in the context of the Zee-Babu neutrino mass model.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.138987.v1/t1","@type":"Dataset","description":"LO, NLO cross-sections and K-factors for the pair-production of doubly charged Higgs bosons in pp collisions at $\\sqrt{s}$ = 13...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.138987.v1/t2","@type":"Dataset","description":"Observed (solid line) and expected (dashed line) 95% CL upper limits on the $H^{\\pm\\pm}$ pair production cross-section as a function...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.138987.v1/t3","@type":"Dataset","description":"Distribution of $m(e^{\\pm},e^{\\pm})_{\\mathrm{lead}}$ in the electron-electron signal region after the background-only fit.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.138987.v1/t4","@type":"Dataset","description":"Distribution of $m(e^{\\pm},\\mu^{\\pm})_{\\mathrm{lead}}$ in the electron-muon signal region after the background-only fit.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.138987.v1/t5","@type":"Dataset","description":"Distribution of $m(\\mu^{\\pm},\\mu^{\\pm})_{\\mathrm{lead}}$ in the muon-muon signal region after the background-only fit.","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.138987.v1/t6","@type":"Dataset","description":"Distribution of $m(\\ell^{\\pm},\\ell^{\\prime \\pm})_{\\mathrm{lead}}$ in the three-lepton signal region after the background-only fit.","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.138987.v1/t7","@type":"Dataset","description":"Event yield in the four-lepton signal region after the background-only fit.","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.138987.v1/t8","@type":"Dataset","description":"Two-lepton signal region weighted cutflows for electron-electron channel.
