摘要
We present an estimate of certain higher-order corrections to the contribution of the charm triangle loop in the inclusive (B) over bar-->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.
