Alam, M. et al. (1995) First measurement of the rate for the inclusive radiative penguin decay b→sγ. Physical Review Letters, 74(15), pp. 2885-2889. (doi: 10.1103/PhysRevLett.74.2885)

Abstract

We have measured the inclusive b→sγ branching ratio to be (2.32±0.57±0.35)×10^-4, where the first error is statistical and the second is systematic. Upper and lower limits on the branching ratio, each at 95% C.L., are B(b→sγ)<4.2×10^-4 and B(b→sγ)>1.0×10^-4. These limits restrict the parameters of extensions of the standard model.
