Description
We investigate the semileptonic B−c→ ̄νll X decays with X(=X(3930),X(3940),X(4160)) resonances. We take into account these resonances as dynamically generated from the vector–vector interaction in the charm sector. The X(3930) and X(3940) states are D∗ ̄D∗ molecules and the X(4160) is D∗s ̄D∗s molecule. We also look at the production of D∗ ̄D∗ and D∗s ̄D∗s close to threshold and we make predictions of the ratio of this differential mass distribution to the rate of production of the X resonances.
