Abstract: (arXiv)

We analyze the inclusive semileptonic

B \to X_c \ell\nu

structure functions in 2+1-flavor lattice QCD. The M\"obius domain-wall fermion action is used for light, strange, charm and bottom quarks. The structure function receives contributions from various exclusive modes, including the dominant S-wave states

D^{(*)}_s

as well as the P-wave states

D_s^{**}

. We can identify them in the lattice data, from which we put some constraints on the

B_s \to D_s^{**}\ell\nu

form factors.
