Scientific paper

We consider the possibility of measuring sin(2β) in the KM unitarity triangle using the process B0-->D*+D*-Ks. This decay mode has a higher branching fraction (O(1%)) than the mode B0-->D*+D*-. We use the factorization assumption and heavy hadron chiral perturbation theory to estimate the branching fraction and polarization. The time dependent rate B0(t)-->D*+D*-Ks can be used to measure sin(2β) and cos(2β). Furthermore, examination of the D*+Ks mass spectrum may be the best way to experimentally find the broad 1+p-wave Ds meson.
