S. Moretti et Wj. Stirling, CONTRIBUTIONS OF BELOW-THRESHOLD DECAYS TO MSSM HIGGS BRANCHING RATIOS, Physics letters. Section B, 347(3-4), 1995, pp. 291-299
We calculate all the experimentally relevant branching ratios of the H
iggs bosons of the Minimal Supersymmetric Standard Model, paying parti
cular attention to the contributions from below-threshold decays. We s
how that in some cases these can significantly change the pattern of b
ranching ratios calculated without taking off-shell effects into accou
nt.
