Measurement of Branching Fractions and Charge Asymmetries in B Meson Decays to {eta}{prime}K*, {eta}{prime}{rho}, and {eta}{pi}
- SLAC
The authors present preliminary measurements of branching fractions and charge asymmetries for the B meson decays B {yields} {eta}{prime} K*, B {yields} {eta}{prime}{rho}, and B{sup +} {yields} {eta}{prime}{pi}{sup +}. The data were recorded with the BABAR detector at PEP-II and correspond to 89 x 10{sup 6} B{bar B} pairs produced in e{sup +}e{sup -} annihilation through the {Upsilon}(4S) resonance. They find the branching fractions {Beta}(B{sup 0} {yields} {eta}K*{sup 0}) = (19.0{sub -2.1}{sup +2.2} {+-} 1.3) x 10{sup -6}, {Beta}(B{sup +} {yields} {eta}K*{sup +}) = (25.7{sub -3.6}{sup +3.8} {+-} 1.8) x 10{sup -6} with 90% confidence, and {Beta}(B{sup +} {yields} {eta}{prime}{pi}{sup +}) = (2.8{sub -1.0}{sup +1.3} {+-} 0.3) x 10{sup -6} (<4.5 x 10{sup -6}). They also set 90% CL upper limits of {Beta}(B{sup 0} {yields} {eta}{prime}K*{sup 0}) < 6.4 x 10{sup -6} and {Beta}(B{sup +} {yields} {eta}{prime}K*{sup +}) < 12 x 10{sup -6}. The time-integrated charge asymmetries are A{sub ch}({eta}K*{sup 0}) = +0.03 {+-} 0.11 {+-} 0.02, A{sub ch}({eta}K*{sup +}) = +0.15 {+-} 0.14 {+-} 0.02, and A{sub ch}({eta}{rho}{sup +}) = +0.06 {+-} 0.29 {+-} 0.02.
