摘要

Using 121.4fb^-1 of data collected with the Belle detector at the Υ{hooked}(5S) resonance at the KEKB asymmetric-energy e⁺e^- collider, we report evidence for the B̄s0→Λc+Λ̄π- decay mode with a measured branching fraction (3.6±1.1[stat.]-0.5+0.3[syst.]±0.9[Λc+]±0.7[NB̄s0])×10-4 and a significance of 4.4 standard deviations. This is the first evidence for a baryonic Bs0 decay.

N2 - Using 121.4fb-1 of data collected with the Belle detector at the Υ{hooked}(5S) resonance at the KEKB asymmetric-energy e+e- collider, we report evidence for the B̄s0→Λc+Λ̄π- decay mode with a measured branching fraction (3.6±1.1[stat.]-0.5+0.3[syst.]±0.9[Λc+]±0.7[NB̄s0])×10-4 and a significance of 4.4 standard deviations. This is the first evidence for a baryonic Bs0 decay.
