Abstract
in the decay channel B 0 J / K 0 S performed with 1.0 fb -1 of pp collisions at s = 7 TeV collected by the LHCb experiment. The fit to the data yields S J / K 0 S = 0.73 0.07 (stat) 0.04 (syst) and C J / K 0 S = 0.03 0.09 (stat) 0.01 (syst). Both values are consistent with the current world averages and within expectations from the Standard Model.
