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.
