Measurement of the branching fraction for the decay $B^0 \to D^{*+} D^{*-}$
B. Aubert, S. Yellin, G. Simi, S. Trincaz-Duvoid et autres
Decays of the type B --> D^{(*)} anti-D^{(*)} can be used to provide a measurement of the parameter sin2beta of the Unitarity Triangle that is complementary to the measurement derived from the mode B^0 --> J/psi K_s^0. In this document we report …
