Approximate next-to-next-to-leading-order threshold resummation in heavy flavor decays / Aglietti, U ; Ricciardi, G
We present an approximate next-to-next-to-leading-order evaluation of the QCD form factor resumming large logarithmic perturbative contributions in semi-inclusive heavy flavor decays. (15 refs)..

A new model-independent way of extracting |$V_{ub}/V_{cb}$| / Aglietti, Ugo (CERN) ; Ciuchini, Marco (Rome III U. ; INFN, Rome3) ; Gambino, Paolo (CERN)
The ratio between the photon spectrum in B -> X_s gamma and the differential semileptonic rate wrt the hadronic variable M_X/E_X is a short-distance quantity calculable in perturbation theory and independent of the Fermi motion of the b quark in the B meson. We present a NLO analysis of this ratio and show how it can be used to determine |V_ub/V_cb| independently of any model for the shape function. [...]

A new sum rule to determine $|V_{ub}|/|V_{cb}|$ / Aglietti, U. (CERN)

Resummed $B \to X_{u}l\nu$ Decay Distributions to Next-to-Leading Order / Aglietti, U (CERN)
We perform factorization of the most general distribution in semileptonic B -> X_u decays and we resum the threshold logarithms to next-to-leading-order. From this (triple-differential) distribution, any other distribution is obtained by integration. [...]

Next-to-leading resummed coefficient function for the shape function / Aglietti, U. (CERN)
We present a next-to-leading evaluation of the resummed coefficient function for the shape function. The results confirm our previous leading order analysis, namely that the coefficient function is short-distance-dominated, and allow relating the shape function computed with a non-perturbative technique to the physical QCD distributions..
