Abstract

The first observation of the decay B0s → anti-D0 K− π+ is reported. The analysis is based on a data sample, corresponding to an integrated luminosity of 1.0 fb^−1 of pp collisions, collected with the LHCb detector. The branching fraction relative to that of the topologically similar decay B0 → anti-D0 π+ π− is measured to be B(B0s → anti-D0 K− π+)/B(B0 → anti-D0 π+ π−) = 1.18 ± 0.05(stat) ± 0.12(syst). In addition, the relative branching fraction of the decay B0 → anti-D0 K+ π− is measured to be B(B0 → anti-D0 K+ π−)/B(B0 → anti-D0 π+ π−) = 0.106 ± 0.007(stat) ± 0.008(syst).
