Determining the sign of the b → sγ amplitude

Determining the sign of the b → sγ amplitude

The latest Belle and BABAR measurements of the inclusive B̄ → Xsl+l- branching ratio have smaller errors and lower central values than the previous ones. We point out that these results indicate that the sign of the b → sγ amplitude is the same as in the standard model. This underscores the importan...
