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…
Renormalization of non-local gluon operators in lattice perturbation theory
Demetrianos Gavriel, Haralambos Panagopoulos, Gregoris Spanoudes
In this study, we investigate the renormalization of a complete set of gauge-invariant non-local gluon operators up to one-loop in lattice perturbation theory. Our computations hav…
Mass effects on the QCD -function
Marios Costa, Demetrianos Gavriel, Haralambos Panagopoulos +1
In this study we present lattice results on the QCD -function in the presence of quark masses. The -function is calculated to three loops in perturbation theory and for impro…
Nucleon axial and pseudoscalar form factors using twisted-mass fermion ensembles at the physical point
Constantia Alexandrou, Simone Bacchio, Martha Constantinou +6
We compute the nucleon axial and pseudoscalar form factors using three 2+1+1 twisted mass fermion ensembles with all quark masses tuned to approximately their physical values…
Nonperturbative renormalization of asymmetric staple-shaped operators in twisted mass lattice QCD
Constantia Alexandrou, Simone Bacchio, Krzysztof Cichy +8
Staple-shaped Wilson line operators are necessary for the study of transverse momentum-dependent parton distribution functions (TMDPDFs) in lattice QCD and beyond. In this work, we…
