Abstract

This Letter reports a measurement of the CP violation observables SJ/ψKS0 and CJ/ψKS0 in the decay channel B0→J/ψKS0 performed with 1.0 fb−11.0 fb−1 of pp collisions at s=7 TeV collected by the LHCb experiment. The fit to the data yields SJ/ψKS0=0.73±0.07(stat)±0.04(syst) and CJ/ψKS0=0.03±0.09(stat)±0.01(syst). Both values are consistent with the current world averages and within expectations from the Standard Model.
