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…
Beta-function, Renormalons and the Mass Term from Perturbative Wilson Loops
G. Burgio, F. Di Renzo, L. Scorzato +1
Several Wilson loops on several lattice sizes are computed in Perturbation Theory via a stochastic method. Applications include: Renormalons, the Mass Term in Heavy Quark Effective…
The basis of the physical Hilbert space of lattice gauge theories
G. Burgio, R. De Pietri, H. A. Morales-Tecotl +2
Non-linear Fourier analysis on compact groups is used to construct an orthonormal basis of the physical (gauge invariant) Hilbert space of Hamiltonian lattice gauge theories. In pa…
