Fermionic decays of neutral MSSM Higgs bosons at the one-loop level
Abstract
The results of a complete one-loop calculation for the fermionic decay width h0, H0, A0 -> f bar(f) of the neutral MSSM Higgs bosons are presented and the dominant light Higgs decay channel h0 -> b bar(b) is discussed in detail. The enhancement of the partial decay width h0 -> b bar(b) compared to the standard Higgs decay is shown for pseudoscalar masses MA < 300 GeV. Simpler approximation formulae for the Higgs decays are given and their quality is discussed by introducing an effective neutral scalar mixing angle sin(alpha)eff. Finally the Higgs branching ratios in b bar(b), c bar(c), tau+ tau- are calculated.
