Abstract: A flavour-tagged time-dependent angular analysis of Bs0→J/ψϕ decays is presented where the J/ψ meson is reconstructed through its decay to an e+e- pair. The analysis uses a sample of pp collision data recorded with the LHCb experiment at centre-of-mass energies of 7 and 8,Te V, corresponding to an integrated luminosity of 3,fb-1. The CP-violating phase and lifetime parameters of the Bs0 system are measured to be ϕs=0.00±0.28±0.07,rad, ΔΓs=0.115±0.045±0.011,ps-1 and Γs=0.608±0.018±0.012,ps-1 where the first uncertainty is statistical and the second systematic. This is the first time that CP-violating parameters are measured in the Bs0→J/ψϕ decay with an e+e- pair in the final state. The results are consistent with previous measurements in other channels and with the Standard Model predictions.
