Coulomb Artifacts and Breakdown of Perturbative Matching in Lattice NRQCD
A. A. Penin, A. Rayyan
By studying an explicit analytical solution of the Coulomb problem on the lattice we demonstrate a breakdown of perturbative matching for the description of the Coulomb artifacts i…

Coulomb Artifacts and Bottomonium Hyperfine Splitting in Lattice NRQCD
Tao Liu, Alexander A. Penin, Ahmed Rayyan
We study the role of the lattice artifacts associated with the Coulomb binding effects in the analysis of the heavy quarkonium within lattice NRQCD. We find that a "naive" perturba…
