A novel framework for spectral density reconstruction via quadrature-based Laplace inversion
Marco Aliberti, Francesco Di Renzo, Petros Dimopoulos +1
In this work, we explore a numerical approach for performing the inverse Laplace transformation, with an emphasis on achieving stability and robustness under noisy conditions. Our…
Lattice artifacts proportional to the quark mass in the QCD running coupling
Marios Costa, Demetrianos Gavriel, Haralambos Panagopoulos +1
Discretization artifacts proportional to the quark mass can limit the precision of strong-coupling determinations in lattice QCD, especially in the presence of heavy quarks. In thi…
Perturbative determination of improvement on the QCD running coupling
Marios Costa, Demetrianos Gavriel, Haralambos Panagopoulos +1
We present the perturbative results of the discretization errors proportional to the quark mass () on the QCD running coupling within lattice perturbation theory.…
Gluon nonlocal operator mixing in lattice QCD
Demetrianos Gavriel, Haralambos Panagopoulos, Gregoris Spanoudes
In this study, we explore the renormalization of a comprehensive set of gauge-invariant gluon nonlocal operators on the lattice. We calculate the renormalization factors for these…
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…
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…
