Study of the Decays B{sup -} {yields} D*{sup +}{pi}{sup -}{pi}{sup -}
- SLAC
We report on analyses of B{sup -} mesons decaying into D*{sup +}{pi}{sup -}{pi}{sup -} and D{sup +}{pi}{sup -}{pi}{sup -} final states using 89 million B{sup -} decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory. Preliminary measurements are given for the inclusive branching fractions for B{sup -} {yields} D*{sup +}{pi}{sup -}{pi}{sup -} and B{sup -} {yields} D*{sup +}{pi}{sup -}{pi}{sup -}, and for the exclusive branching fractions for B{sup -} {yields} D{sub 1}(2420){sup 0}{pi}{sup -} and B{sup -} {yields} D*{sub 2}(2460){sup 0}{pi}{sup -}, where D{sub 1}(2420){sup 0} and D*{sub 2}(2460){sup 0} are the two narrow c{bar u} P-wave states. The ratio {Beta}(B{sup -} {yields} D*{sub 2}(2460){sup 0}{pi}{sup -})/{Beta}(B{sup -} {yields} D{sub 1}(2420){sup 0}{pi}{sup -}) is measured to be 0.80 {+-} 0.07 {+-} 0.16.
