Looking for quantum SUSY signatures in top quark decays at hadron colliders

We discuss the supersymmetric quantum effects on top quark decays within the MSSM. It turns out that t-> H+ b is the most promising candidate for carrying large quantum SUSY signatures. As a result, the recent (tan(beta) M_H) exclusion plots presented by the CDF Collaboration should be thoroughly revised in the light of the MSSM.
