This book was released on 2005 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a sample of 232 x 106 [Upsilon](4S) 2!B{bar B} events collected with the BABAR detector, we study the decay B 2!p{bar p}K excluding charmonium decays to p{bar p}. We measure a branching fraction [Beta](B+ 2!p{bar p}K+) = (6.7 ± 0.5 ± 0.4) x 10−6. An enhancement at low p{bar p} mass is observed and the Dalitz plot asymmetry suggests dominance of the penguin amplitude in this B decay. We search for a pentaquark candidate [Theta]*{sup ++} decaying into pK+ in the mass range 1.43 to 2.00 GeV/c2 and set limits on [Beta](B+ 2![Theta]*{sup ++} {bar p}) x [Beta]([Theta]*{sup ++} 2!pK+) at the 10−7 level.

Download or read book Measurement of the Branching Fraction for the Decay B°--]D{sup *+}D{sup *-} written by and published by . This book was released on 2001 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decays of the type B 2!D{sup (*)} {bar D}(*) can be used to provide a measurement of the parameter sin2[beta] of the Unitarity Triangle that is complementary to the measurement derived from the mode B° 2!K{sub S}°. In this document we report a measurement of the branching fraction for the decay B° 2!D*D*− with the BABAR detector. With data corresponding to an integrated luminosity of 20.7 fb−1 collected at the [Upsilon](4S) resonance during 1999-2000, we have reconstructed 38 candidate signal events in the mode B° 2!D*D*− with an estimated background of 6.2 ± 0.5 events. From these events, we determine the branching fraction to be [Beta](B° 2!D*+D*−) = (8.0 ± 1.6(stat) ± 1.2(syst)) x 10−4 (preliminary). The measured fraction of the component with odd CP parity is 0.27± 0.17(stat) ± 0.02(syst).
