Studies on finite-volume effects in the inclusive semileptonic decays of charmed mesons
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 were approximately tuned to the physical values. We cover the whole kinematical region. The focus of this work is on the systematic error due to finite-volume effects. We construct a model of two-body final states to describe the data on a finite volume lattice of L≃0.055fm to investigate the extrapolation to the infinite-volume limit.

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 were approximately tuned to the physical values. We cover the whole kinematical region. The focus of this work is on the systematic error due to finite-volume effects. We construct a model of two-body final states to describe the data on a finite volume lattice of L≃0.055fm to investigate the extrapolation to the infinite-volume limit.
