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 B0 s → J/ψη decay mode, τeff, is measured to be τeff = 1.479 ± 0.034 (stat) ± 0.011 (syst) ps. Assuming CP conservation, τeff corresponds to the lifetime of the light B0 s mass eigenstate. This is the first measurement of the effective lifetime in this decay mode.
