Four-quark operators with in the GIRS scheme
M. Constantinou, M. Costa, H. Herodotou +2
We calculate the mixing matrices of four-quark operators that change flavor numbers by two units. Our approach employs two schemes: the coordinate-space Gauge Invariant Renormaliza…
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 the Gluino-Glue operator
Marios Costa, George Panagopoulos, Haralambos Panagopoulos +1
We study the Gluino-Glue operator in the context of Supersymmetric Yang-Mills (SYM) theory. This composite operator is gauge invariant, and it is directly connected…
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…
