Description
The exclusive decay modes B→Kγγ and Bs→η(η')γγ are shown to have significant branching ratios of approximately 0.5x10-7. This first calculation of these modes employs a model based on a cascade transition B→Vγ→Pγγ for estimating the long-distance contribution and the process b→sγγ for the short-distance one. copyright 1997 The American Physical Society
