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 Gamma;(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider.

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 Gamma;(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.
