Full O($\alpha_S$) Evaluation for $b \to s\gamma$ Transverse Momentum Distribution

The full O(alpha_S) transverse momentum distribution for the b -> s+gamma decay is computed. Results are presented in analytic form. An improved expression for the coefficient function taking into account subleading operators is given and an exact expression for the remainder function associated...

description The full O(alpha_S) transverse momentum distribution for the b -> s+gamma decay is computed. Results are presented in analytic form. An improved expression for the coefficient function taking into account subleading operators is given and an exact expression for the remainder function associated with the leading operator O_7 is also derived.
