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…
Supersymmetric QCD: Renormalization and Mixing of Composite Operators
M. Costa, H. Panagopoulos
We study -dimensional SQCD with gauge group and flavors of chiral super-multiplets on the lattice. We perform extensive calculations of matrix elements and renor…
matrix elements of the chromomagnetic operator on the lattice
M. Constantinou, M. Costa, R. Frezzotti +5
We present the results of the first lattice QCD calculation of the matrix elements of the chromomagnetic operator , which appears i…
Supersymmetric QCD on the Lattice: An Exploratory Study
M. Costa, H. Panagopoulos
We perform a pilot study of the perturbative renormalization of a Supersymmetric gauge theory with matter fields on the lattice. As a specific example, we consider Supersymmetric $…
One-loop calculations in Supersymmetric Lattice QCD
M. Costa, H. Panagopoulos
We study the self energies of all particles which appear in a lattice regularization of supersymmetric QCD (). We compute, perturbatively to one-loop, the relevant two-…
Perturbative and non-perturbative renormalization results of the Chromomagnetic Operator on the Lattice
M. Constantinou, M. Costa, R. Frezzotti +5
The Chromomagnetic operator (CMO) mixes with a large number of operators under renormalization. We identify which operators can mix with the CMO, at the quantum level. Even in dime…
