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…
Two-loop renormalization and mixing of gluon and quark energy-momentum tensor operators
George Panagopoulos, Haralambos Panagopoulos, Gregoris Spanoudes
In this paper, we present one- and two-loop results for the renormalization of the gluon and quark gauge-invariant operators which appear in the definition of the QCD energy-moment…
