Recent Results on QCD Corrections to Semileptonic $b$-Decays
Abstract
We summarize recent results on QCD corrections to various observables in semileptonic quark decays. For massless leptons in the final state we present effects of such corrections on triple differential distribution of leptons which are important in studies of polarized quark decays. Analogous formulas for distributions of neutrinos are applicable in decays of polarized quarks. In the case of decays with a lepton in the final state mass effect of has to be included. In this case we concentrate on corrections to the total decay width.
