Xsγ Branching Fraction 2010 .txt text/plain 368 26 60 Radiative decays of B-mesons are ideal laboratories for probing New Physics (NP). New Physics particles can potentially propagate in this loop, and if the NP couplings are comparableto those of the SM, deviations from the SM prediction of the B ? cache/hx11xd09r02.txt txt/hx11xd09r02.txt
