Description

Utilizing the approach recently proposed for the inclusive semi-leptonic decay rate on the lattice, we compute the differential decay rate of a B_s meson for various kinematical channels. The results are compared with the contributions from the ground states (D and D) as well as from the orbitally excited states (D*'s). The computation so far is carried out with an unphysically light bottom quark and strange spectator quark.
