Quantum chromodynamics

The European Physical Journal C, 2000
AbstractThe strong interactions were the last of the fundamental forces in the twentieth century to be fully understood in terms of basic and fundamental equations. Shortly after the discovery of the renormalizable non‐Abelian gauge theories that unified the electroweak forces, it was realized that the strong force had to be described by such a gauge ...

The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post-War Period. [PDF]

Ber Wiss
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Gravitational wave signatures of phase transition from hadronic to quark matter in isolated neutron stars and binaries [PDF]

EPJ Web of Conferences, 2022
The fundamental constituent of matter at high temperature and density has intrigued physicists for quite some time. Recent results from heavy-ion colliders have enriched the Quantum Chromodynamics phase diagram at high temperatures and low baryon density.

Quantum simulation of colour in perturbative quantum chromodynamics

SciPost Physics, 2023
Quantum computers are expected to give major speed-ups for the simulation of quantum systems. In this work, we present quantum gates that simulate the colour part of the interactions of quarks and gluons in perturbative quantum chromodynamics (QCD). As a

50 Years of quantum chromodynamics

European Physical Journal C: Particles and Fields, 2023
Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be described by a local SU(3) gauge symmetry with charges called “color quantum numbers”, is reviewed; the goal of this review is to provide advanced Ph.D.

Calculation of the Rate of Photons Emission from Charm-Gluon Interaction

Journal of Kufa-Physics, 2023
In this research, the rate of photons emission from quark-gluon interaction based on the quantum chromodynamics theory was calculated. The rate of photons emission was evaluated for

Differential Dyson–Schwinger equations for quantum chromodynamics

European Physical Journal C: Particles and Fields, 2020
Using a technique devised by Bender, Milton and Savage, we derive the Dyson–Schwinger equations for quantum chromodynamics in differential form. We stop our analysis to the two-point functions.

Diamagnetic and paramagnetic phases in low-energy quantum chromodynamics

Physics Letters B, 2021
While it is known that the QCD vacuum in a magnetic background exhibits both diamagnetic and paramagnetic characteristics in the low-energy domain, a systematic investigation of the corresponding phases emerging in the pion-dominated regime is still ...

The L ∞ structure of gauge theories with matter

Journal of High Energy Physics, 2021
In this work we present an algebraic approach to the dynamics and perturbation theory at tree-level for gauge theories coupled to matter. The field theories we will consider are: Chern-Simons-Matter, Quantum Chromodynamics, and scalar Quantum ...
