Abstract

We report the results of the first search for Standard Model and baryon-number-violating two-body decays of the neutral B mesons to Λ0 and Ωc(*)0 using 711  fb−1 of data collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. We observe no evidence of signal from any such decays and set 95% confidence-level upper limits on the products of B0 and B¯0 branching fractions for these two-body decays with B(Ωc0→π+Ω−) in the range between 9.5×10−8 and 31.2×10−8.
