Search for neutral Higgs Bosons Production in Final States with b-quarks in the semi-leptonic channel — •Antonio Vagnerini — Desy
The LHC discovery of a Standard-Model like Higgs particle in 2012 motivates searches of additional Higgs bosons predicted both in the Minimal-Supersymmetry Extension of the SM and the two-Higgs doublet model. These are characterised by heavy Higgs states with large branching fractions for decays into b-quarks. This analysis focuses on the semi-leptonic channel, which has significantly lower trigger rates for low transverse momentum (pT) jets than the full-hadronic channel. B-hadrons have a large component of semi-leptonic decays, hence the presence of muons in final states is a probe for b-tagging. The new upgraded semi-leptonic trigger development and validation is also presented. Finally, we determine upper limits in the sensitivity analysis to complement and extend the reach of the high-pT jet full-hadronic analysis.
