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 Bs 0→J/ψη decay mode, τeff, is measured to beτeff=1.479±0.034 (stat)±0.011 (syst) ps. Assuming CP conservation, τeff corresponds to the lifetime of the light Bs 0 mass eigenstate. This is the first measurement of the effective lifetime in this decay mode. © 2016 The Author

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 Bs0→J/ψη decay mode, τeff, is measured to beτeff=1.479�0.034 (stat)�0.011 (syst) ps. Assuming CP conservation, τeffcorresponds to the lifetime of the light Bs0mass eigenstate. This is the first measurement of the effective lifetime in this decay mode.
