Measurement of the ratio of branching fractions B(B0→K⁎0γ)/B(Bs0→ϕγ) and the direct CP asymmetry in B0→K⁎0γ

R. Aaij, C. Abellán Beteta, A. Adametz, B. Adeva et autres

The ratio of branching fractions of the radiative B decays B0→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 …

First observation of B¯s0→Ds2⁎+Xμ−ν¯ decays

R. Aaij, B. Adeva, M. Adinolfi, C. Adrover et autres

Using data collected with the LHCb detector in proton–proton collisions at a centre-of-mass energy of 7 TeV, the semileptonic decays B¯s0→Ds+Xμ−ν¯ and B¯s0→D0K+Xμ−ν¯ are detected. Two structures are observed in the D0K+ mass spectrum at masses consistent with the known Ds1(2536)+ and …
