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 Y(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 B0-bar 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.

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 Y(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 B0-bar 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.File in questo prodotto:
