Scientific paper

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 sqrts = 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 to 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 (Delta_b corrections) in the MSSM are consistently taken into account. Two benchmark scenarios are considered, one of them the `mhmax'.
