Nonperturbative properties of Yang–Mills theories

MQ Huber - Physics Reports, 2020 - Elsevier
Yang–Mills theories are an important building block of the standard model and in particular
of quantum chromodynamics. Its correlation functions describe the behavior of its …

Gauge bosons at zero and finite temperature

A Maas - Physics Reports, 2013 - Elsevier
Gauge theories of the Yang–Mills type are the single most important building block of the
standard model of particle physics and beyond. They are an integral part of the strong and …

Causality, unitarity and stability in quantum gravity: a non-perturbative perspective

A Platania - Journal of High Energy Physics, 2022 - Springer
A bstract Resumming quantum fluctuations at the level of the gravitational path integral is
expected to result in non-local effective actions and thus in a non-trivial momentum …

Reconstructing the gluon

AK Cyrol, JM Pawlowski, A Rothkopf, N Wink - SciPost Physics, 2018 - scipost.org
We reconstruct the gluon spectral function in Landau gauge QCD from numerical data for
the gluon propagator. The reconstruction relies on two novel ingredients: Firstly we derive …

High precision statistical Landau gauge lattice gluon propagator computation vs. the Gribov–Zwanziger approach

D Dudal, O Oliveira, PJ Silva - Annals of Physics, 2018 - Elsevier
In this article we report on lattice results for the Landau gauge gluon propagator using large
statistical ensembles. In particular, the compatibility of the lattice data with the tree level …

Local and BRST-invariant Yang-Mills theory within the Gribov horizon

MAL Capri, D Dudal, D Fiorentini, MS Guimaraes… - Physical Review D, 2016 - APS
We present a local setup for the recently introduced BRST-invariant formulation of Yang-
Mills theories for linear covariant gauges that takes into account the existence of gauge …

[HTML][HTML] Spectral representation of lattice gluon and ghost propagators at zero temperature

D Dudal, O Oliveira, M Roelfs, P Silva - Nuclear Physics B, 2020 - Elsevier
We consider the analytic continuation of Euclidean propagator data obtained from 4D
simulations to Minkowski space. In order to perform this continuation, the common approach …

Glueball masses from an infrared moment problem

D Dudal, MS Guimaraes, SP Sorella - Physical Review Letters, 2011 - APS
We set up an infrared-based moment problem to obtain estimates of the masses of the
scalar, pseudoscalar, and tensor glueballs in Euclidean Yang-Mills theories using the …

Massless mode and positivity violation in hot QCD

N Su, K Tywoniuk - Physical Review Letters, 2015 - APS
We calculate the quark self-energy at one-loop level at high temperature, taking into account
contributions from both the (chromo) electric scale g T and the (chromo) magnetic scale g 2 …

Analytic structure of QCD propagators in Minkowski space

F Siringo - Physical Review D, 2016 - APS
Analytical functions for the propagators of QCD, including a set of chiral quarks, are derived
by a one-loop massive expansion in the Landau gauge, deep in the infrared. By analytic …
