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

Journal article

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 underscores the importance of B -->Xsl+l- in searches for new physics, and may be relevant for neutralino-dark matter analyses within the minimal supersymmetric standard model.
