002918282 520__ $$9arXiv$$aWe report on the calculation of the inclusive semileptonic decay of the $D_s$ meson on the lattice. We simulate the $D_s \rightarrow X_s\ell\nu_\ell$ process with Möbius domain-wall charm and strange quarks, whose masses are approximately tuned to their physical values. Our simulations cover the whole kinematical region. The focus of this work is to present updates on our strategies towards estimating the systematic uncertainties in the determination of the inclusive decay rate. We specifically focus on the systematic errors due to the choice of our approximation strategy and finite-volume effects.

Right: A comparison of the model prediction and the lattice data for the finite-volume corrections. The model prediction is obtained for the smeared and unsmeared kernel, respectively, as a function of the threshold value $\omega_{\text{th}}$ for two volumes $V=48^3$ (dashed) and $256^3$ (dotted). The smeared kernel is denoted with $\sigma$ in the subscript. The lattice data are obtained using the Chebyshev approximation for the full data set.
