Measurement of Branching Fractions and CP-Violating Asymmetries in B -> rho+/-h-/+
Abstract
We present measurements of branching fractions and CP-violating asymmetries in B{sup 0} {yields} {rho}{sup {+-}}{pi}{sup {-+}} and B{sup 0} {yields} {rho}{sup -}K{sup +} decays. The results are obtained from a data sample of 88.9 x 10{sup 6} {Upsilon}(4S) {yields} B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. From a time-dependent maximum likelihood fit we measure the charge-averaged branching fractions {Beta}(B{sup 0} {yields} {rho}{sup {+-}}{pi}{sup {-+}}) = (22.6 {+-} 1.8 (stat) {+-} 2.2 (syst)) x 10{sup -6} and {Beta}(B{sup 0} {yields} {rho}{sup -}K{sup +}) = (7.3{sub -1.2}{sup +1.3} {+-} 1.3) x 10{sup -6}; and the CP-violating charge asymmetries A{sub CP}{sup {rho}{pi}} = -0.18 {+-} 0.08 {+-} 0.03 and A{sub CP}{sup {rho}K} = 0.28 {+-} 0.17 {+-} 0.08; the direct CP violation parameter C{sub {rho}{pi}} = 0.36 {+-} 0.18 {+-} 0.04 and the mixing-induced CP violation parameter S{sub {rho}{pi}} = 0.19 {+-} 0.24 {+-} 0.03; and the dilution parameters {Delta}C{sub {rho}{pi}} = 0.28{sub -0.19}{sup +0.18} {+-} 0.04 and {Delta}S{sub {rho}{pi}} = 0.15 {+-} 0.25 {+-} 0.03.
