- Abstract:
-
The ratio of branching fractions of the radiative B decays B0→K *0γ and B0s→φγ has been measured using 0.37fb -1 of pp collisions at a center of mass energy of √s=7TeV, collected by the LHCb experiment. The value obtained is B(B0→K *0γ)B(B0s→φγ)=1.12±0.08- 0.04-0.08+0.06+0.09, where the first uncertainty is statistical, the second systematic, and the third is associated with the ratio of fragmentation fractions f s/f d. Using the world average for B(B0→K *0γ)=(4.33±0.15)×10 -5, the branching ...
