 Title: Search for doubly charged Higgs boson production in multi-lepton final states with the ATLAS detector using proton–proton collisions at ?s=13TeV Authors: The ATLAS CollaborationSultansoy, Saleh Keywords: Collisionsjetsproton–proton collisions Issue Date: Mar-2018 Publisher: Springer New York LLC Source: ATLAS collaboration. (2018). Search for doubly charged Higgs boson production in multi-lepton final states with the ATLAS detector using proton–proton collisions at $$\sqrt {s}= 13\,\text {TeV}$$. The European Physical Journal C, 78(3), 199. Abstract: 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±?± and H± ±? ?±?±, 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 ?±?±= e±e±/ ?±?±/ e±?±, the observed lower limit on the mass of a doubly charged Higgs boson only coupling to left-handed leptons varies from 770 to 870 GeV (850 GeV expected) for B(H± ±? ?±?±) = 100 % and both the expected and observed mass limits are above 450 GeV for B(H± ±? ?±?±) = 10 % and any combination of partial branching ratios. © 2018, CERN for the benefit of the ATLAS collaboration.
