Description
We present a pilot study on extracting the P-wave form factors of the $B_s$ to $D_s$ semi-leptonic decays from the Bs four-point correlators. With their inclusive nature, four-point correlators include all the exclusive states from Bs with valence content of c and s quarks. We access the P-wave form factors by excluding the contributions from the S-wave final states. In this pilot study, 2+1-flavour domain-wall fermion actions with approximately physical masses are utilized for light quarks. Heavy quarks, c and b, are simulated using relativistic-heavy quark actions. A single lattice ensemble with a lattice spacing of 0.11 fm is used for the analysis.
