Measurement of Branching Fractions and Charge Asymmetries in B+/- -->rho+/-pi0 and B+/- -->rho0pi+/- Decays, and Search for B0 --> rho0pi0
- SLAC
The authors present measurements of branching fractions and charge asymmetries in B-meson decays to {rho}{sup +}{pi}{sup 0}, {rho}{sup 0}{pi}{sup +} and {rho}{sup 0}{pi}{sup 0}. The data sample comprises 89 x 10{sup 6} {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetries-energy B Factory at SLAC. They find the charge-averaged branching fractions {Beta}(B{sup +} {yields} {rho}{sup +}{pi}{sup 0}) = (10.9 {+-} 1.9(stat) {+-} 1.9(syst)) x 10{sup -6} and {Beta}(B{sup +} {yields} {rho}{sup 0}{pi}{sup +}) = (9.5 {+-} 1.1 {+-} 0.8) x 10{sup -6}, and they set a 90% confidence-level upper limit {Beta}(B{sup 0} {yields} {rho}{sup 0}{pi}{sup 0}) < 2.9 x 10{sup -6}. The authors measure the charge asymmetries A{sub CP}{sup {rho}{sup +}{pi}{sup 0}} = 0.24 {+-} 0.16 {+-} 0.06 and A{sub CP}{sup {rho}{sup 0}{pi}{sup +}} = -0.19 {+-} 0.11 {+-} 0.02.
