|V_{cb}| from semileptonic B decays with two-loop QCD accuracy

Abstract

Recent progress in calculating O(alpha_s^2) corrections to inclusive and exclusive semileptonic b-->c transitions is reviewed. The impact of these corrections on the |V_cb| determination from both inclusive and exclusive B decays is discussed.
