Determining the sign of the b-->sgamma amplitude.

Determining the sign of the b-->sgamma amplitude.

Show other versions (1)

The latest Belle and BABAR measurements of the inclusive B -->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-->sgamma amplitude is the same as in the standard model. This unders...
