Using Heavy Quark Spin Symmetry in Semileptonic Bc Decays
Abstract
The form factors parameterizing the Bc semileptonic matrix elements can be related to a few invariant functions if the decoupling of the spin of the heavy quarks in Bc and in the mesons produced in the semileptonic decays is exploited. We compute the form factors as overlap integral of the meson wave-functions obtained using a QCD relativistic potential model, and give predictions for semileptonic and non-leptonic Bc decay modes. We also discuss possible experimental tests of the heavy quark spin symmetry in Bc decays.
