Three loop calculations and inclusive Vcb
We discuss the impact of the recent O(αs3) calculations of the semileptonic width of the b quark and of the relation between pole and kinetic heavy quark masses by Fael et al. on the inclusive determination of |Vcb|. The most notable effect is a reduction of the uncertainty. Our final result is |Vcb...
