Transverse Momentum Distributions in B-Decays
arXiv:hep-ph/0105322 · doi:10.1016/S0370-2693(01)01280-1
Abstract
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 large logarithmic contributions is performed in impact parameter space within the general formalism for transverese momentum distributions. It is shown that the shape-function approach as used for the threshold distribution case cannot be extended to the transverse momentum one.
