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…
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…
Perturbative renormalization factors and O(a^2) corrections for lattice 4-fermion operators with improved fermion/gluon actions
Martha Constantinou, Petros Dimopoulos, Roberto Frezzotti +4
In this work we calculate the corrections to the amputated Green's functions of 4-fermion operators, in 1-loop Lattice Perturbation theory. One of the novel aspects of our calculat…
BK-parameter from Nf = 2 twisted mass lattice QCD
ETM Collaboration, M. Constantinou, P. Dimopoulos +12
We present an unquenched lattice computation of the parameter which controls oscillations. A partially quenched setup is employed with two maximally…
Two-loop renormalization of fermion bilinear operators on the lattice
A. Skouroupathis, H. Panagopoulos
We compute the renormalization functions on the lattice, in the RI' scheme, of local bilinear quark operators , where . This calculation…
