Description
Inclusive semileptonic B decays offer a possibility to test the Standard
Model (SM) in its flavor structure. The relevant SM parameters are the
quark mixing parameters that accompany these types of decays, gathered
in the CKM matrix. In my talk I'm going to present the technique to
determine the inclusive width of a heavy flavored meson which allow to
extract the CKM matrix elements $V_{qb}$. As an approach we use the
Heavy quark expansion and calculate analytically the perturbative QCD
corrections to the power suppressed contribution of the chromo-magnetic
operator. In the calculation the final state quark is treated as massless.
