Hybrid static potentials from Laplacian Eigenmodes

High Energy Physics - Lattice 2024-01-19 v1

Abstract

We present a method for computing hybrid static quark-antiquark potentials in lattice QCD based on Laplace trial states. They are formed by eigenvector components of the covariant lattice Laplace operator and their covariant derivatives. The new method does not need complicated gauge link paths between the static quarks and makes off-axis separations easily accessible. We show first results for Σ\Sigma and Π\Pi together with their excited states on a dynamical ensemble.
