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…

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…
