Abstract

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