Supercurrent Renormalization in Supersymmetric Yang-Mills Theory
Georg Bergner, Marios Costa, Haralambos Panagopoulos +4
In this work we study the renormalization of the SUSY Noether current in Supersymmetric = 1 Yang-Mills (SYM) theory on the lattice. In particular, we study the mixing…
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…
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…
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…
