QCD Corrections to the Light Higgs Boson Decay into a Charm- Anticharm or Bottom- Antibottom Pair within the Minimal Supersymmetric Model
Abstract
We present the results of the contributions to the decay rate of the lightest Higgs particle into a charm-anticharm and bottom-antibottom pair within the minimal supersymmetric standard model when scalar quarks and a gluino are taken within the relevant loop diagrams. We show that in the case where the vacuum expectation values of the Higgs particles obey the condition v1 v2\ the scalar quarks and gluino change the decay rate by not more than a few per cent. These small contributions make it difficult to distinguish the Higgs particle of the standard model from the supersymmetric one.
