Contribution
It introduces a 2+2 anisotropic lattice framework, computes one-loop gluon self-energy corrections, and examines Lorentz invariance restoration, extending previous 3+1 analyses.
Findings

Analyzed Lorentz invariance restoration in on-shell states
Extended Wilson fermion actions to 2+2 discretization
Abstract
A generalization of anisotropic lattices to include a 2+2 discretization is discussed. As a part of this program, we determine the one-loop correction to the gluon self-energy and analyse the restoration of Lorentz invariance in on-shell states for both the 2+2 and 3+1 cases. A 2+2 Wilson-like fermion action is also considered.
