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…
