Measurement of the B s 0 → J / ψ η lifetime

Measurement of the B s 0 → J / ψ η lifetime

© 2016 The Author 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.
