Gauge-invariant renormalization of four-quark operators
M. Constantinou, M. Costa, H. Herodotou +2
We study the renormalization of four-quark operators in one-loop perturbation theory. We employ a coordinate-space Gauge-Invariant Renormalization Scheme (GIRS), which can be advan…
Renormalization of asymmetric staple-shaped Wilson-line operators in lattice and continuum perturbation theory
Gregoris Spanoudes, Martha Constantinou, Haralambos Panagopoulos
In this work, we study the renormalization of nonlocal quark bilinear operators containing an asymmetric staple-shaped Wilson line at the one-loop level in both lattice and continu…
Perturbative study of renormalization and mixing for asymmetric staple-shaped Wilson-line operators on the lattice
Gregoris Spanoudes, Martha Constantinou, Haralambos Panagopoulos
We present one-loop perturbative results of the renormalization functions for a complete set of nonlocal quark bilinear operators containing an asymmetric staple-shaped Wilson line…
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…
Perturbative Renormalization of Wilson line operators
M. Constantinou, H. Panagopoulos
We present results for the renormalization of gauge invariant nonlocal fermion operators which contain a Wilson line, to one loop level in lattice perturbation theory. Our calculat…
Singlet vs Nonsinglet Perturbative Renormalization of Fermion Bilinears
M. Constantinou, M. Hadjiantonis, H. Panagopoulos +1
In this paper we present the perturbative evaluation of the difference between the renormalization functions of flavor singlet and nonsinglet bilinear quark operators on the lattic…
