Measurement of CP observables in B0DK0 with DK+K / LHCb Collaboration
The decay B0DK0 and the charge conjugate mode are studied using 1.0fb1 of pp collision data collected by the LHCb experiment at s=7TeV in 2011. The CP asymmetry between the B0DK0 and the ˉB0DˉK0 decay rates, with the neutral D meson in the CP-even final state K+K, is found to be AKKd=0.45±0.23±0.02, where the first uncertainty is statistical and the second is systematic.
