Measurement of the ratio of branching fractions B ( B 0 → K ⁎ 0 γ ) / B ( B s 0 → ϕ γ ) and the direct CP asymmetry in B 0 → K ⁎ 0 γ
The ratio of branching fractions of the radiative B decays B 0→K *0γ and Bs0→φγ has been measured using an integrated luminosity of 1.0 fb -1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s=7 TeV. The value obtained isB(B0→K*0γ)B(Bs0→φγ)=1.23±0.06 (stat.)±0.04 (...
