Quantum chromodynamics (QCD) is the established non-Abelian gauge theory of the strong force, governing the interactions of quarks and gluons through the SU(3) colour symmetry. Its hallmark ...

Quarks and antiquarks are the teeny, tiny building blocks with which all matter is built, binding together to form protons and neutrons in a process explained by quantum chromodynamics (QCD).

Artist’s depiction of a proton’s interior. In quantum chromodynamics, the constituent quarks come in three “colors,” along with up and down “flavors.” Also shown are virtual quark-antiquark pairs and ...

Quantum chromodynamics (QCD) is the theory that describes the interactions governed by the strong nuclear force. Where electromagnetism is mediated by the photon and the weak force by the W and Z ...

Created as an analogy for Quantum Electrodynamics (QED) — which describes the interactions due to the electromagnetic force carried by photons — Quantum Chromodynamics (QCD) is the theory of physics ...

The life and death of a star can largely be described based on its mass. Below the Chandrasekhar limit—about 1.4 times the mass of the sun—a star will end its life as a white dwarf. Stars that weigh ...

A study describes a new technique for simulating particle ensembles that are 'large' (at least by the standards of particle physics). The technique improves the signal-to-noise ratio and thus the ...

Quantum Chromodynamics (QCD) is universally accepted today as the theory of strong interactions. Nevertheless, many conceptual questions, like those concerning the properties of the quark gluon plasma ...
