英文摘要 | A search for doubly charged higgs bosons with pairs of prompt, isolated, highly energetic leptons with the same electric charge is presented. the search uses a proton-proton collision data sample at a centre-of-mass energy of 13 tev corresponding to 36.1 fb(-1) of integrated luminosity recorded in 2015 and 2016 by the atlas detector at the lhc. this analysis focuses on the decays h-+/-+/- -> e(+/-)e(+/-), h-+/-+/- -> e(+/-)mu(+/-) and h-+/-+/- -> mu(+/-)mu(+/-), fitting the dilepton mass spectra in several exclusive signal regions. no significant evidence of a signal is observed and corresponding limits on the production cross-section and consequently a lower limit on m(h-+/-+/-) are derived at 95% confidence level. with l(+/-)l(+/-) = e(+/-)e(+/-)/mu(+/-)mu(+/-)/e(+/-)mu(+/-), the observed lower limit on the mass of a doubly charged higgs boson only coupling to left-handed leptons varies from 770 to 870gev (850gev expected) for b(h-+/-+/- -> l(+/-)l(+/-)) = 100% and both the expected and observed mass limits are above 450gev for b(h-+/-+/- -> l(+/-)l(+/-)) = 10% and any combination of partial branching ratios. |
