Gauge sector dynamics in QCD

MN Ferreira, J Papavassiliou - Particles, 2023 - mdpi.com
The dynamics of the QCD gauge sector give rise to non-perturbative phenomena that are
crucial for the internal consistency of the theory; most notably, they account for the …

Emergent hadron mass in strong dynamics

D Binosi - Few-Body Systems, 2022 - Springer
Abstract Emergent Hadron Mass (EHM) is a mechanism capable of explaining both the
unnaturally small (pion) and large (proton) masses of hadrons and if not the origin of …

QCD phase structure at finite temperature and density

W Fu, JM Pawlowski, F Rennecke - Physical Review D, 2020 - APS
We discuss the phase structure of QCD for N f= 2 and N f= 2+ 1 dynamical quark flavors at
finite temperature and baryon chemical potential. It emerges dynamically from the …

Landau gauge Yang-Mills correlation functions

AK Cyrol, L Fister, M Mitter, JM Pawlowski, N Strodthoff - Physical Review D, 2016 - APS
We investigate Landau gauge SU (3) Yang-Mills theory in a systematic vertex expansion
scheme for the effective action with the functional renormalization group. Particular focus is …

Fully coupled functional equations for the quark sector of QCD

F Gao, J Papavassiliou, JM Pawlowski - Physical Review D, 2021 - APS
We present a comprehensive study of the quark sector of 2+ 1 flavor QCD, based on a self-
consistent treatment of the coupled system of Schwinger-Dyson equations for the quark …

Emergence of mass in the gauge sector of QCD

J Papavassiliou - Chinese Physics C, 2022 - iopscience.iop.org
It is currently widely accepted that gluons, while massless at the level of the fundamental
QCD Lagrangian, acquire an effective mass through the non-Abelian implementation of the …

Schwinger mechanism revisited

F Gelis, N Tanji - Progress in Particle and Nuclear Physics, 2016 - Elsevier
In this article, we review recent theoretical works on the Schwinger mechanism of particle
production in external electrical fields. Although the non-perturbative Schwinger mechanism …

Exploring smoking-gun signals of the Schwinger mechanism in QCD

AC Aguilar, MN Ferreira, J Papavassiliou - Physical Review D, 2022 - APS
In Quantum Chromodynamics, the Schwinger mechanism endows the gluons with an
effective mass through the dynamical formation of massless bound-state poles that are …

Gluon propagator and three-gluon vertex with dynamical quarks

AC Aguilar, F De Soto, MN Ferreira… - The European Physical …, 2020 - Springer
We present a detailed analysis of the kinetic and mass terms associated with the Landau
gauge gluon propagator in the presence of dynamical quarks, and a comprehensive …

Ghost dynamics in the soft gluon limit

AC Aguilar, CO Ambrósio, F De Soto, MN Ferreira… - Physical Review D, 2021 - APS
We present a detailed study of the dynamics associated with the ghost sector of quenched
QCD in the Landau gauge, where the relevant dynamical equations are supplemented with …
