Abstract
Charged Higgs bosons are predicted in several extensions of the Standard Model, where the Higgs sector contains more than one doublet of complex scalars, for instance in the Minimal Supersymmetric Standard Model (MSSM). For mH+ < mtop, the dominant production mode for charged Higgs bosons at the LHC is via the decay t → bH+ of one of the top quarks in events. We present results on the search for such light charged Higgs bosons in the ATLAS experiment, with emphasis on the decay H+ → τν.

The result in data is compared to Monte Carlo (MC) and the ratio is used as a scale factor in MC
Summary
One major task for the Large Hadron Collider (LHC) and the ATLAS experiment is the exploration of the Higgs sector in the Standard Model (SM) and beyond it. The type-II 2HDM is considered, which is the Higgs sector of the Minimal Supersymmetric Standard Model (MSSM) [2]. The searches for the charged Higgs boson in ttevents (see Fig. 1) with one or two light charged leptons (i.e. electrons or muons) in the final state [4] and in the case where both the τ and the W boson decay hadronically (τ+jets channel) [5] are described. This study describes the search for the charged Higgs boson in ttevents which decay into [H+b][W−b] and into [(τ+had mass
