Classification of four-quark operators with under flavor symmetry and their renormalization in a gauge-invariant scheme
Gregoris Spanoudes, Marios Costa, Kyproulla Mitsidi +1
In this paper we study a complete set of scalar and pseudoscalar four-quark operators, with a particular emphasis on their renormalization within a Gauge-Invariant Renormalization…
N=1 Supersymmetric QCD on the lattice using overlap fermions
Marios Costa, Eleni Ioannou, Haralambos Panagopoulos
Using N=1 Supersymmetric QCD (SQCD) as a prototype model, this work presents a formulation of overlap quarks and gluinos on the lattice, with particular emphasis on the constructio…
Perturbative determination of improvement on the QCD running coupling
Marios Costa, Demetrianos Gavriel, Haralambos Panagopoulos +1
We present the perturbative results of the discretization errors proportional to the quark mass () on the QCD running coupling within lattice perturbation theory.…
