Study on the P-wave form factors contributing to Bs to Ds inclusive semileptonic decays from lattice simulations
We present a pilot study on extracting the form factors of the semileptonic decay of a Bs meson to the P-wave D∗∗s states from Bs four-point correlators. With their inclusive nature, four-point correlators include contributions from all possible final states. From the extracted P-wave form factors, we obtain numerical results for the corresponding Isgur-Wise form factors. The results suggest significant contributions from radial excitations to the Uraltsev sum rule at zero-recoil. In this pilot study, a coarse lattice of 243×64 with lattice spacing of 0.11fm is used for the analysis.

Abstract
We present a pilot study on extracting the form factors of the semileptonic decay of a Bs meson to the P-wave D∗∗s states from Bs four-point correlators. With their inclusive nature, four-point correlators include contributions from all possible final states. From the extracted P-wave form factors, we obtain numerical results for the corresponding Isgur-Wise form factors. The results suggest significant contributions from radial excitations to the Uraltsev sum rule at zero-recoil. In this pilot study, a coarse lattice of 243×64 with lattice spacing of 0.11fm is used for the analysis.
