| Summary: | A search is conducted for a low-mass charged Higgs boson produced in a top quark decay and subsequently
decaying into a charm and a strange quark. The data sample was recorded in proton-proton collisions at ffiffi
s p ¼ 13 TeV by the CMS experiment at the LHC and corresponds to an integrated luminosity of 35.9 fb−1.
The search is performed in the process of top quark pair production, where one top quark decays to a bottom
quark and a charged Higgs boson and the other to a bottom quark and a W boson. With the W boson decaying
to a charged lepton (electron or muon) and a neutrino, the final state comprises an isolated lepton, missing
transverse momentum, and at least four jets, of which two are tagged as b jets. To enhance the search
sensitivity, one of the jets originating from the charged Higgs boson is required to satisfy a charm tagging
selection. No significant excess beyond standard model predictions is found in the dijet invariant mass
distribution. An upper limit in the range 1.68%–0.25% is set on the branching fraction of the top quark decay to
the charged Higgs boson and bottom quark for a charged Higgs boson mass between 80 and 160 GeV. |
