Top decays into lighter stop and gluino

Abstract

We have calculated the decay width of the process $t\to \tilde{g}{\tilde{t}}_1$ including one loop QCD corrections. We found that the decay width of the such process could be comparable with that of the standard channel $t\to b{W}^{+}$, and, its QCD correction could enhance the widths over 30% in a very large mass range of the lighter stop.
