The 2+2 anisotropic Wilson gluon action with applications
Giuseppe Burgio, Alessandra Feo, Mike Peardon +1
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…

Matrix elements of the plaquette operator of Lattice Gauge Theory
G. Burgio, R. De Pietri, H. A. Morales-Tecotl +2
We show that in the spin-network basis it is possible to compute the matrix elements of any given operator of the Hamiltonian formulation of Lattice Gauge Theory (LGT). We give the…

Search for 1/p^2 Corrections to the Running QCD Coupling
G. Burgio, F. Di Renzo, C. Parrinello +1
We investigate the occurrence of power terms in the running QCD coupling by analysing non-perturbative measurements of alpha_s (p) at low momenta obtained from the lattice three-gl…
