Gauge-fixed Lattice QCD and the dispersion relation of Wilson fermions

Blog Article

We show that, when investigating Wilson-fermions correlation functions on the lattice, one is bound to encounter major difficulties in defining their dispersion relation, even at tree level.The problem is indeed quite general and, argan oil pure purple although we stumbled upon it while studying Coulomb-gauge iphone 13 dallas applications, it also affects gauge fixed studies in covariant gauges, including their most popular version, Landau gauge.In this paper we will discuss a solution to this problems based on a redefinition of the kinematic momentum of the fermion.
