Abstract:
Results on the search for a light charged Higgs boson decaying to in top quark pair events using the CMS detector at the LHC are presented. %It is the first search for a charged Higgs boson in this decay mode. The total dataset corresponds to 19.7 of proton-proton collisions at = 8 TeV. In decays, if one top quark decays to , instead of , and the subsequently decays to , while other top quark decays leptonically (), the final state then consists of four jets (three quark jets), one lepton (electron or muon), and missing energy:
. The main observable used in the analysis is an invariant mass of two jets, one of which is identified as a b quark jet.
The dijet pair is selected from at least four jets in an event by a dedicated kinematic fitter. No signal for the presence of a charged Higgs boson is observed and upper limits are set at 95\% confidence level on the branching ratio for
from 1.1--0.4\% for the charged Higgs boson mass in the range 90--150~GeV in the assumption of branching ratio of for the first time.Note:
