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 ...
Search for CP violation using T-odd correlations in D 0 → K + K −π+π− decays
A search for CP violation using T-odd correlations is performed using the four-body D 0 → K + K −π+π− decay, selected from semileptonic B decays. The data sample corresponds to integrated luminosities of 1.0 fb−1 and 2.0 ...
Measurement of the CKM angle γ using B± → DK± with D → K0Sπ+π−, K0SK+K− decays
A binned Dalitz plot analysis of B± → DK± decays, with D → K 0Sπ+π− and D → K 0SK+K−, is used to perform a measurement of the CP-violating observables x± and y±, which are sensitive to the Cabibbo-Kobayashi-Maskawa angle ...
