Measurement of the Effective B[superscript 0][subscript s]→J/ΨK[superscript 0][subscript S] Lifetime
This paper reports the first measurement of the effective B[superscript 0][subscript s] →J/ψK[superscript 0][subscript S] 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....

| description | This paper reports the first measurement of the effective B[superscript 0][subscript s] →J/ψK[superscript 0][subscript S] 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[superscript -1] of pp collisions, recorded by the LHCb experiment in 2011 at a centre-of-mass energy of 7 TeV. The results are: τ[superscript eff] [subscript J/ψK[superscript 0][subscript S]] = 1.75±0.12 (stat)±0.07 (syst) ps and B(B[superscript 0][subscript S] →J/ψK[superscript 0][subscript S]) = (1.97 ± 0.23) × 10[superscript -5]. For the latter measurement, the uncertainty includes both statistical and systematic sources. © 2013 CERN. Published by Elsevier B.V. |
