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 Creator T-Shirt difficulties in defining their dispersion relation, even at tree level.The problem is indeed quite general and, although we stumbled upon it while studying Coulomb-gauge applications, it also affects gauge fixed studies in covariant gauges, including their most popular version, Landau gauge.In this Laundry - Bags and Liners paper we will discuss a solution to this problems based on a redefinition of the kinematic momentum of the fermion.
