This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present a measurement of the B{sup 0} {center_dot} {bar {Lambda}}p{pi}{sup -} branching fraction performed using the BABAR detector at the PEP-II asymmetric energy e{sup +}e{sup -} collider. Based on a 232 million B{bar B} pairs data sample we measure: {center_dot} (B{sup 0} {center_dot} {bar {Lambda}}p{pi}{sup -}) = [3.30 {center_dot} 0.53(stat.) {center_dot} 0.31 (syst.)] {center_dot} 10{sup -6}. A measurement of the differential spectrum as a function of the di-baryon invariant mass m({Lambda}p) is also presented; this shows a near-threshold enhancement similar to that observed in other baryonic B decays.
