Abstract

The first observation of the B0s → anti-D0 K0S decay mode and evidence for the B0s → anti-D∗0 K0S decay mode are reported. The data sample corresponds to an integrated luminosity of 3.0 fb^−1 collected in pp collisions by LHCb at center-of-mass energies of 7 and 8 TeV. The branching fractions are measured to be B(B0s → anti-D0 anti-K0) = [4.3 ± 0.5(stat) ± 0.3(syst) ± 0.3(frag) ± 0.6(norm)] × 10^−4, B(B0s → anti-D*0 anti-K0) = [2.8 ± 1.0(stat) ± 0.3(syst) ± 0.2(frag) ± 0.4(norm)] × 10^−4, where the uncertainties are due to contributions coming from statistical precision, systematic effects, and the precision of two external inputs, the ratio f_s/f_d and the branching fraction of B0 → anti-D0 K0S, which is used as a calibration channel.
