Measurement of the effective B → J/ψK lifetime

This paper reports the first measurement of the effective B →J/ψK lifetime and an updated measurement of its time-integrated branching fraction. Both measurements are performed with a data sample, corresponding to an integrated luminosity of 1.0 fb of pp collisions, recorded by the LHCb experiment...
