Impact of SUSY-QCD corrections on top quark decay distributions
We compute the supersymmetric QCD corrections to the decay distribution of polarized top quarks for the semileptonic decay mode $t(\uparrow)\to b l^+ν_l$. As a byproduct, we reinvestigate the SUSY-QCD corrections to the total decay width $Γ(t\to W^+b)$ and resolve a discrepancy between two previous results in the literature.
