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…
Supersymmetric QCD on the lattice: Fine-tuning and counterterms for the Yukawa and quartic couplings
M. Costa, H. Herodotou, H. Panagopoulos
In this study, we determine the fine-tuning of parameters in Supersymmetric QCD, discretized on a Euclidean lattice. Our focus is on the renormalization of Yukawa…
Supersymmetric QCD on the lattice: Fine-tuning and counterterms for the quartic couplings
Marios Costa, Herodotos Herodotou, Haralambos Panagopoulos
In this work we calculate the renormalization of counterterms which arise in the lattice action of Supersymmetric QCD (SQCD). In particular, the fine-tunings for quartic co…
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…
Renormalization of the Yukawa and Quartic Couplings in Supersymmetric QCD
M. Costa, H. Herodotou, H. Panagopoulos
In this work we perform calculations in order to determine the renormalization factors and the mixing coefficients of the Yukawa and the quartic couplings in Supe…
Supersymmetric QCD on the Lattice: Fine-Tuning of the Yukawa Couplings
Marios Costa, Herodotos Herodotou
We determine the fine-tuning of the Yukawa couplings of supersymmetric QCD, discretized on a lattice. We use perturbation theory at one-loop level. The Modified Minimal Subtraction…
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…
Perturbative study of the Gluino-Glue operator in SYM
Marios Costa, George Panagopoulos, Haralambos Panagopoulos +3
We investigate the renormalization of the Gluino-Glue operator, using both Lattice Perturbation Theory (LPT) and a Gauge Invariant Renormalization Scheme (GIRS). The latter scheme…
Renormalization and Mixing of the Gluino-Glue Operator on the Lattice
Marios Costa, Herodotos Herodotou, Phivos Philippides +1
We study the mixing of the Gluino-Glue operator in =1 Supersymmetric Yang-Mills theory (SYM), both in dimensional regularization and on the lattice. We calculate its reno…
