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…
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…
Improving perturbation theory with cactus diagrams
Martha Constantinou, Haralambos Panagopoulos, Apostolos Skouroupathis
We study a systematic improvement of perturbation theory for gauge fields on the lattice [hep-lat/0606001]; the improvement entails resumming, to all orders in the coupling constan…
