Nucleon charges and -terms in lattice QCD
C. Alexandrou, S. Bacchio, J. Finkenrath +4
We determine the nucleon axial, scalar and tensor charges and the nucleon -terms using twisted mass fermions. We employ three ensembles with approximately equal physical volume…
Renormalization of nonlocal gluon operators on the lattice
Demetrianos Gavriel, Haralambos Panagopoulos, Gregoris Spanoudes
We study the renormalization of a complete set of gauge-invariant gluon nonlocal operators in lattice perturbation theory. We determine the mixing pattern under renormalization of…
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…
Quark and gluon momentum fractions in the pion and in the kaon
Constantia Alexandrou, Simone Bacchio, Martha Constantinou +9
We present the full decomposition of the momentum fraction carried by quarks and gluons in the pion and the kaon. We employ three gauge ensembles generated with Wilson…
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…
