Abstract
We study for the first time the three-body charmless baryonic decays B¯s0âp¯ÎM+(pίMâ), with M=Ï,K. We find that the branching ratios of B¯s0â(p¯ÎK+ and pίKâ) and B¯s0âpίÏâ are (5.1±1.1)Ã10â6 and (2.8±1.5)Ã10â7, respectively, which agree with recent experimental results reported by the LHCb collaboration. In addition, we derive the relations B(B¯s0âp¯ÎK+)â(fK/fÏ)2(ÏBs0/ÏB0)B(B¯0âp¯ÎÏ+) and B(B¯s0âpίÏâ)/B(B¯s0âpίKâ)âB(Bââpp¯Ïâ)/B(Bââpp¯Kâ) to be confronted to future experimental measurements. The fact that all four processes Bs0,B¯s0âpίKâ,p¯ÎK+ can occur opens the possibility of decay-time-dependent CP violation measurements in baryonic B decays, something that had not been realized before.
