Transverse Momentum Distributions in B-Decays
U. Aglietti, R. Sghedoni, L. Trentadue
We consider transverse momentum distributions in B-decays. The O(alpha_S) coefficients for soft and collinear logarithms are computed to next-to-leading accuracy. Resummation of la…
The shape function in field theory
U. Aglietti
The shape function describes (non-perturbative) Fermi motion effects in semi-inclusive heavy flavour decay. Its renormalization properties are substantially dependent on the kind o…
Effective Theories for Exclusive and Seminclusive Processes and Factorization
U. Aglietti
The effective theories for massless quarks describing exclusive and seminclusive processes are discussed, considering in particular the factorization problem.
Model independent determination of the light-cone wave functions for exclusive processes
U. Aglietti, M. Ciuchini, G. Corbo' +3
We present a method to compute, by numerical simulations of lattice QCD, the light-cone wave functions which enter exclusive processes at large momentum transfer, such as electroma…
