Evidence for Bs0 -> Lambdac+ Lambda-bar pi-
Abstract
Using 121.4 fb-1 of data collected with the Belle detector at the Y(5S) resonance at the KEKB asymmetric-energy e+e- collider, we report evidence for the Bs0 -> Lambdac+ Lambda-bar pi- decay mode with a measured branching fraction (3.6 +- 1.1[stat.] +0.3 -0.5[syst.] +- 0.9[Lambdac+] +- 0.7[NBs]) * 10-4 and a significance of 4.4 standard deviations. This is the first evidence for a baryonic Bs0 decay.
