Abstract

The charged Higgs boson is a smoking gun of extensions of the standard model with multiple Higgs doublets, and has been searched for at various collider experiments. In this paper, we study the signature of a light charged Higgs boson produced by top quark pairs at the Large Hadron Collider (LHC), with subsequent three-body decays into a W boson and a pair of bottom quarks. Cross sections on final states of two W bosons plus four bottom quarks have been measured by the ATLAS Collaboration at the LHC 13 TeV. We reinterpret the experimental data under the scenario of a light charged Higgs boson and find improved agreements. We obtain the first limit from LHC direct searches on the total branching ratio of the three-body decay, Br(t→H+b)×Br(H+→W+bb¯), and the strongest direct constraints on the parameter space of a class of type-I two-Higgs-doublet models.
