Insights into the emergence of mass from studies of pion and kaon structure

CD Roberts, DG Richards, T Horn, L Chang - Progress in Particle and …, 2021 - Elsevier
There are two mass generating mechanisms in the standard model of particle physics (SM).
One is related to the Higgs boson and fairly well understood. The other is embedded in …

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 …

From controversy to precision on the sigma meson: a review on the status of the non-ordinary f0 (500) resonance

JR Peláez - Physics Reports, 2016 - Elsevier
The existence and properties of the sigma meson have been controversial for almost six
decades, despite playing a central role in the spontaneous chiral symmetry of QCD or in the …

Emergence of hadron mass and structure

M Ding, CD Roberts, SM Schmidt - Particles, 2023 - mdpi.com
Visible matter is characterised by a single mass scale; namely, the proton mass. The
proton's existence and structure are supposed to be described by quantum chromodynamics …

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 …

Explanation and prediction of observables using continuum strong QCD

IC Cloet, CD Roberts - Progress in Particle and Nuclear Physics, 2014 - Elsevier
The last five years have brought considerable progress in the study of the bound-state
problem in continuum quantum field theory. We highlight a subset of that progress; viz., that …

Collective perspective on advances in Dyson—Schwinger equation QCD

A Bashir, L Chang, IC Cloet, B El-Bennich… - Communications in …, 2012 - iopscience.iop.org
We survey contemporary studies of hadrons and strongly interacting quarks using QCD's
Dyson—Schwinger equations, addressing the following aspects: confinement and …

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 …

Phase structure of three and four flavor QCD

CS Fischer, J Luecker, CA Welzbacher - Physical Review D, 2014 - APS
We investigate the phase structure of QCD at finite temperature and light-quark chemical
potential. We improve upon earlier results for N f= 2+ 1 dynamical quark flavors and …

Bridging a gap between continuum-QCD and ab initio predictions of hadron observables

D Binosi, L Chang, J Papavassiliou, CD Roberts - Physics Letters B, 2015 - Elsevier
Within contemporary hadron physics there are two common methods for determining the
momentum-dependence of the interaction between quarks: the top-down approach, which …
