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...

description | 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 in 2011 at a centre-of-mass energy of 7 TeV. The results are: τ = 1.75±0.12 (stat)±0.07 (syst) ps and B(B →J/ψK ) = (1.97 ± 0.23) × 10. For the latter measurement, the uncertainty includes both statistical and systematic sources. © 2013 CERN.
