Abstract The first observation of the B0sˉD0K0SB0s¯D0K0S decay mode and evidence for the B0sˉD0K0SB0s¯D0K0S decay mode are reported. The data sample corresponds to an integrated luminosity of 3.0 fb1fb1 collected in pppp collisions by LHCb at center-of-mass energies of 7 and 8 TeV. The branching fractions are measured to be B(B0sˉD0ˉK0)=(4.3±0.5(stat)±0.3(syst)±0.3(frag)±0.6(norm))×104,B(B0sˉD0ˉK0)=(2.8±1.0(stat)±0.3(syst)±0.2(frag)±0.4(norm))×104, where the uncertainties are due to contributions coming from statistical precision, systematic effects, and the precision of two external inputs, the ratio fs/fd and the branching fraction of B0ˉD0K0S, which is used as a calibration channel.
