Abstract
A search for doubly charged scalar bosons decaying into W boson pairs is presented. It uses a data sample from proton–proton collisions corresponding to an integrated luminosity of 36.1 fb- 1 collected by the ATLAS detector at the LHC at a centre-of-mass energy of 13 TeV in 2015 and 2016. This search is guided by a model that includes an extension of the Higgs sector through a scalar triplet, leading to a rich phenomenology that includes doubly charged scalar bosons H± ±. Those bosons are produced in pairs in proton–proton collisions and decay predominantly into electroweak gauge bosons H± ±→ W±W±. Experimental signatures with several leptons, missing transverse energy and jets are explored. No significant deviations from the Standard... (More)

The parameter space of the benchmark model is excluded at 95% confidence level for H± ± bosons with masses between 200 and 220 GeV. © 2019, CERN for the benefit of the ATLAS collaboration. (Less)
