Systematic effects in the lattice calculation of inclusive semileptonic decays
Systematic effects in the lattice calculation of inclusive semileptonic decays
We report on the calculation of the inclusive semileptonic decay of the Ds meson on the lattice. We simulate the Ds→Xsℓνℓ 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.

Abstract
We report on the calculation of the inclusive semileptonic decay of the Ds meson on the lattice. We simulate the Ds→Xsℓνℓ 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.
