QCD at finite temperature and chemical potential from Dyson–Schwinger equations

CS Fischer - Progress in Particle and Nuclear Physics, 2019 - Elsevier
We review results for the phase diagram of QCD, the properties of quarks and gluons and
the resulting properties of strongly interacting matter at finite temperature and chemical …

Baryons as relativistic three-quark bound states

G Eichmann, H Sanchis-Alepuz, R Williams… - Progress in Particle and …, 2016 - Elsevier
We review the spectrum and electromagnetic properties of baryons described as relativistic
three-quark bound states within QCD. The composite nature of baryons results in a rich …

Chiral symmetry breaking in continuum QCD

M Mitter, JM Pawlowski, N Strodthoff - Physical Review D, 2015 - APS
We present a quantitative analysis of chiral symmetry breaking in two-flavor continuum QCD
in the quenched limit. The theory is set up at perturbative momenta, where asymptotic …

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 …

Nonperturbative quark, gluon, and meson correlators of unquenched QCD

AK Cyrol, M Mitter, JM Pawlowski, N Strodthoff - Physical Review D, 2018 - APS
We present nonperturbative first-principle results for quark, gluon, and meson 1PI correlation
functions of two-flavor Landau-gauge QCD in the vacuum. These correlation functions carry …

Light mesons in QCD and unquenching effects from the 3PI effective action

R Williams, CS Fischer, W Heupel - Physical Review D, 2016 - APS
We investigate the impact of unquenching effects on QCD Green's functions, in the form of
quark-loop contributions to both the gluon propagator and three-gluon vertex, in a three-loop …

Locating the critical endpoint of QCD: Mesonic backcoupling effects

PJ Gunkel, CS Fischer - Physical Review D, 2021 - APS
We study the effects of pion and sigma meson backcoupling on the chiral order parameters
and the QCD phase diagram and determine their effect on the location of the chiral critical …

Spectrum of scalar and pseudoscalar glueballs from functional methods

MQ Huber, CS Fischer, H Sanchis-Alepuz - The European Physical …, 2020 - Springer
We provide results for the spectrum of scalar and pseudoscalar glueballs in pure Yang–Mills
theory using a parameter-free fully self-contained truncation of Dyson–Schwinger and Bethe …

QCD phase transitions in the light quark chiral limit

J Bernhardt, CS Fischer - Physical Review D, 2023 - APS
We investigate the order of the QCD chiral transition in the limit of vanishing bare up/down
quark masses and variations of the bare strange-quark mass 0≤ ms≤∞. In this limit and …
