Complete bremsstrahlung corrections to the forward-backward asymmetries in $b\to X_s\ell^+\ell^-$

Abstract

In a recent paper we presented a calculation of NNLL virtual corrections to the forward-backward asymmetries in $b\to X_s\ell^+\ell^-$ decay. That result does not include bremsstrahlung corrections which are free from infrared and collinear singularities. In the present paper we include the remaining ${\cal O}(α_s)$ bremsstrahlung corrections to the forward-backward asymmetries in $b\to X_s\ell^+\ell^-$ decay. The numerical effect of the calculated contributions is found to be below 1%.
