Abstract

The first observation of the Bs0D¯0KS0 decay mode and evidence for the Bs0D¯*0KS0 decay mode are reported. The data sample corresponds to an integrated luminosity of 3.0fb1 collected in pp collisions by LHCb at center-of-mass energies of 7 and 8 TeV. The branching fractions are measured to be B(Bs0D¯0K¯0)=[4.3±0.5(stat)±0.3(syst)±0.3(frag)±0.6(norm)]×104,B(Bs0D¯*0K¯0)=[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 B0D¯0KS0, which is used as a calibration channel.
