Comment On Nonperturbative O(1/m_c^2) Corrections to B -> X_s gamma
arXiv:hep-ph/9702380 · doi:10.1103/PhysRevD.56.3151
Abstract
We present an estimate of certain higher order corrections to the contribution of the charm triangle loop in the inclusive B -> X_s gamma decay rate, recently discussed by Voloshin. We find that these corrections are minute and hence the result found by Voloshin, although small, is quite robust.
