Abstract
- 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.<br />Comment: 8 pages, 3 figures; contribution to The 38th International Symposium on Lattice Field Theory, LATTICE2021, 26th-30th July, 2021
