Abstract

The mixing-induced CP-violating phase φsin B0sand B0sdecays is measured using the J/ψπ+π−final state in data, taken from 3fb−1of integrated luminosity, collected with the LHCb detector in 7 and 8TeV centre-of-mass ppcollisions at the LHC. A time-dependent flavour-tagged amplitude analysis, allowing for direct CPviolation, yields a value for the phase φs=70 ±68 ±8mrad. This result is consistent with the Standard Model expectation and previous measurements.
