Cross-sections and branching ratios for charged Higgs searches — •Andre Sopczak — Lancaster University, UK
For the preparation of the experimental search for charged Higgs bosons at the LHC detailed studies have been made to determine the expected charged Higgs boson production cross-sections and decay branching ratios at √s=14 TeV. In the mass regime below the t-quark mass the expected production cross-sections are discussed using PYTHIA and FeynHiggs program packages based on the decay t→ H+b. For higher masses Next-to-Leading-Order (NLO) calculations have been used, and particular attention has been given to the intermediate-mass region. The decay branching ratios have been studied with the program packages FeynHiggs and HDecay. Higher-order corrections (Δb corrections) in the MSSM are consistently taken into account. Two benchmark scenarios are considered, one of them the ‘mhmax’.
