Comment On Nonperturbative O(1/mc2) Corrections to B -> Xs gamma
A. K. Grant, A. G. Morgan, S. Nussinov, R. D. Peccei
Abstract
We present an estimate of certain higher order corrections to the contribution of the charm triangle loop in the inclusive B -> Xs 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.
