$D_{s}$ Lifetime, $m_{b}$ , $m_{c}$ and $∣ V_{c b} ∣$ in the Heavy Quark Expansion

I. I. Bigi, N. G. Uraltsev

We present some straightforward applications of the QCD heavy quark expansion, stated in previous papers [1-3], to the inclusive widths of heavy flavour hadrons. We address the que…

Weak Annihilation and the Endpoint Spectrum in Semileptonic B Decays

I. I. Bigi, N. G. Uraltsev

A general relationship is formulated between the contributions of `Weak Annihilation' (WA) to inclusive semileptonic decays of heavy flavour hadrons and the matrix elements of four…
