Abstract

Using a data set corresponding to an integrated luminosity of 3 fb⁻¹, collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV, the effective lifetime in the B_s ⁰→J/ψη decay mode, τ_eff, is measured to beτ_eff=1.479±0.034 (stat)±0.011 (syst) ps. Assuming CP conservation, τ_eff corresponds to the lifetime of the light B_s ⁰ mass eigenstate. This is the first measurement of the effective lifetime in this decay mode.
