Precision Measurement of C P Violation and Branching Fractions in B ± → K S 0 h ± ( h = π , K ) Decays and Search for the Rare Decay B c ± → K S 0 K ±

R. Aaij, A. S. W. Abdelmotteleb, Carlos Abellán Beteta, F. Abudinén et autres

The decay B^{±}→K_{S}^{0}π^{±}, with a CP asymmetry expected to be close to zero in the standard model, is theoretically clean and sensitive to potential new physics. An analysis of the decays B^{±}→K_{S}^{0}π^{±} and B^{±}→K_{S}^{0}K^{±} is performed using proton-proton collision data collected by …

Observation of new excited $B^0_s$ states

R. Aaij, C. Abellán Beteta, T. Ackernley, B. Adeva et autres

Abstract: A structure is observed in the B±K∓ mass spectrum in a sample of proton–proton collisions at centre-of-mass energies of 7, 8, and 13 TeV, collected with the LHCb detector and corresponding to a total integrated luminosity of 9fb-1. The structure is …

Measurement of the Bs0→J/ψKS0 branching fraction

R. Aaij, Carlos Abellán Beteta, B. Adeva, M. Adinolfi et autres

The Bs0→J/ψKS0 branching fraction is measured in a data sample corresponding to 0.41fb−1 of integrated luminosity collected with the LHCb detector at the LHC. This channel is sensitive to the penguin contributions affecting the sin2β measurement from B0→J/ψKS0. The time-integrated branching fraction …
