Determination of |Vcb| using N3LO perturbative corrections to Γ(B → Xcℓν) and 1S masses
We determine |Vcb| using the third-order perturbative series for the inclusive semileptonic B decay width and for the masses of the bottomonium 1S states. We use the masses of ηb(1S) and ϒ(1S) as short-distance masses and point out that there is a sizable difference of |Vcb| between the two 1S mass...
