Gauge-invariant renormalization of four-quark operators
M. Constantinou, M. Costa, H. Herodotou +2
We study the renormalization of four-quark operators in one-loop perturbation theory. We employ a coordinate-space Gauge-Invariant Renormalization Scheme (GIRS), which can be advan…
Fine-Tuning of the Yukawa and Quartic Couplings in Supersymmetric QCD
M. Costa, H. Herodotou, H. Panagopoulos
In this work, we investigate the fine tuning of parameters in Supersymmetric QCD, discretized on a Euclidean lattice. Specifically, we study the renormalization o…
Nonperturbative renormalization of the supercurrent in Supersymmetric Yang-Mills Theory
Georg Bergner, Marios Costa, Haralambos Panagopoulos +3
In this work, we study the nonperturbative renormalization of the supercurrent operator in Supersymmetric Yang-Mills (SYM) theory, using a gauge-invariant renorma…
Gauge-invariant renormalization of fermion bilinears and energy-momentum tensor on the lattice
G. Spanoudes, M. Costa, I. Karpasitis +4
We study a gauge-invariant renormalization scheme (GIRS) for composite operators, regularized on the lattice, by extending the coordinate space (X-space) scheme proposed some years…
Gauge-invariant Renormalization Scheme in QCD: Application to fermion bilinears and the energy-momentum tensor
M. Costa, I. Karpasitis, G. Panagopoulos +4
We consider a gauge-invariant, mass-independent prescription for renormalizing composite operators, regularized on the lattice, in the spirit of the coordinate space (X-space) reno…
Supersymmetric QCD on the Lattice: An Exploratory Study
M. Costa, H. Panagopoulos
We perform a pilot study of the perturbative renormalization of a Supersymmetric gauge theory with matter fields on the lattice. As a specific example, we consider Supersymmetric $…
