Title: Study of B --> D*{sup +}D*{sup -} Decays with the BABAR Detector

Abstract

Decays of the type B {yields} D(*){bar D}(*) can be used to provide a measurement of the parameter sin2{beta} of the Unitarity Triangle that is complementary to that derived from the mode B{sup 0} {yields} J/{psi}K{sub S}{sup 0}. Here we report a measurement of the branching fraction and a study of the CP parity content for the decay B{sup 0} {yields} D*{sup +}D*{sup -} with the BABAR detector. With data corresponding to an integrated luminosity of 20.7 fb{sup -1} collected at the {Upsilon}(4S) resonance during 1999-2000, we determine the branching fraction to be {Beta}(B{sup 0} {yields} D*{sup +}D*{sup -}) = (8.0 {+-} 1.6(stat ) {+-} 1.2(syst.)) x 10{sup -4}. The measured fraction of the component with odd CP parity is 0.22 {+-} 0.18(stat) {+-} 0.03(syst). Observation of a significant number of candidates in the decay modes B{sup 0} {yields} D*{sup +}D{sup -} and B{sup +} {yields} D*{sup +}D*{sup 0} is reported. All results presented in this note are preliminary.
