Measurement of the branching fraction and Λ̄ polarization in B0→Λ̄pπ-

Measurement of the branching fraction and Λ̄ polarization in B0→Λ̄pπ-

We present a measurement of the B0→Λ̄pπ- branching fraction performed using the BABAR detector at the PEP-II asymmetric e+e- collider. Based on a sample of 467×106 BB̄ pairs we measure B(B0→Λ̄pπ-)=[3.07±0.31(stat)±0.23(syst)] ×10-6. The measured differential spectrum as a function of the dibaryon in...
