We point out that these results indicate that the sign of the b -> s gamma amplitude is the same as in the SM. This underscores the importance of B -> X_s l^+ l^- in searches for new physics, and may be relevant for neutralino dark matter analyses within the MSSM.Journal version, references added, minor modifications. 4 pages, 2 figuresHigh Energy Physics - PhenomenologyHigh Energy Physics - ExperimentDetermining the sign of the b -> s gamma amplitudetext
