First measurement of the CP-violating phase in B0s→J/ψ( → e+e−)ϕ decays

First measurement of the CP-violating phase in B0s→J/ψ( → e+e−)ϕ decays

A flavour-tagged time-dependent angular analysis of B0s→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...
