Higher representations on the lattice: perturbative studies
Luigi Del Debbio, Mads T. Frandsen, Haralambos Panagopoulos +1
We present analytical results to guide numerical simulations with Wilson fermions in higher representations of the colour group. The ratio of parameters, the additive renormali…
Two-loop additive mass renormalization with clover fermions and Symanzik improved gluons
A. Skouroupathis, M. Constantinou, H. Panagopoulos
We calculate the critical value of the hopping parameter, , in Lattice QCD, up to two loops in perturbation theory. We employ the Sheikholeslami-Wohlert (clover) improved acti…
Gauge theories with overlap fermions in an arbitrary representation: Evaluation of the 3-loop beta-function
M. Constantinou, H. Panagopoulos
This work presents the calculation of the relation between the bare coupling constant g_0 and the MSbar-renormalized coupling g_MS, g_0 = Z_g(g_0,aμ) g_MS, to 2 loops in perturbati…
The Lattice Free Energy of QCD with Clover Fermions, up to Three-Loops
A. Athenodorou, H. Panagopoulos, A. Tsapalis
We calculate the perturbative value of the free energy in Lattice QCD, up to three loops. Our calculation is performed using Wilson gluons and the Sheikholeslami - Wolhert (clover)…
QCD with overlap fermions: Running coupling and the 3-loop beta-function
M. Constantinou, H. Panagopoulos
We calculate the relation between the bare coupling constant g_0 and the MSbar-renormalized coupling g_MS: g_0 = Z_g(g_0,a μ) g_MS, to 2 loops in perturbation theory. We employ the…
Lambda-parameter of lattice QCD with Symanzik improved gluon actions
A. Skouroupathis, H. Panagopoulos
We compute the ratio Lambda_L/Lambda_MS, where the scale parameter Lambda_L is associated with a lattice formulation of QCD. We consider a 3-parameter family of gluon actions, whic…
