$O({\alpha }_s)$ perturbative and nonperturbative corrections to polarized semileptonic ${\Lambda }_b$ decay distributions

Martin Fischer, Stefan Groote

In this paper we calculate first order radiative QCD corrections to the decay process $b\to c{W}^{-}(\to {\ell }^{-}{\bar{\nu }}_{\ell })$ of a polarized bottom quark. Taking into account both the bot…
