The mixing-induced CP-violating phaseφsin Bs0 and B-s0 decays is measured using the J/ψπ +π -final state in data, taken from 3 fb-1of integrated luminosity, collected with the LHCb detector in 7 and 8 TeV centre-of-mass pp collisions at the LHC. A time-dependent flavour-tagged amplitude analysis, allowing for direct CP violation, yields a value for the phaseφs= 70 ± 68 ± 8 mrad. This result is consistent with the Standard Model expectation and previous measurements.
