Measurement of CP violation parameters and polarisation fractions in B0s→J/ψK∗0 decays
The first measurement of CP asymmetries in the decay B0s→J/ψK∗(892)0 and an updated measurement of its branching fraction and polarisation fractions are presented. The results are obtained using data corresponding to an ...
Measurement of CP asymmetry in B0s → D ∓s K± decays
We report on measurements of the time-dependent CP violating observables in B 0s → D ∓s K ± decays using a dataset corresponding to 1.0 fb−1 of pp collisions recorded with the LHCb detector. We find the CP violating ...
Measurement of the CKM angle γ using B ± → DK ± with D → K0S π + π −, K0S K + K − decays
A binned Dalitz plot analysis of B± → DK± decays, with D → K0S + − and D → K0S K+K−, is performed to measure the CP-violating observables x± and y±, which are sensitive to the Cabibbo-Kobayashi-Maskawa angle . The ...
Observation of the Λ0b → J/ψ pπ − decay
The first observation of the Cabibbo-suppressed decay Λ 0b → J/ψpπ − is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb−1. A prominent signal is ...
Measurement of the time-dependent CP asymmetries in B0s → J/ψK0S
The first measurement of decay-time-dependent CP asymmetries in the decay B0s → J/ψK0S and an updated measurement of the ratio of branching fractions B(B0s→J/ψK0S)/B(B0→J/ψK0S)are presented. The results are obtained using ...
