quantum chromodynamics

n. (used with a sing. verb)

quantum chromodynamics

n (functioning as singular)
(Atomic Physics) physics a theory describing the strong interaction in terms of quarks and gluons, with the colour of quarks used as an analogue of charge and the gluon as an analogue of the photon. Abbreviation: QCD
[C20: chromodynamics from chromo- (referring to quark colour) + dynamics, modelled on quantum electrodynamics]

(ˌkroʊ moʊ daɪˈnæm ɪks)
n.
(used with a sing. v.) a quantum theory of the interactions of quarks and gluons in which the color of quarks is analogous to electric charge. Abbr.: QCD

Noun1.quantum chromodynamics - a theory of strong interactions between elementary particles (including the interaction that binds protons and neutrons in the nucleus); it assumes that strongly interacting particles (hadrons) are made of quarks and that gluons bind the quarks together
quantum field theory - the branch of quantum physics that is concerned with the theory of fields; it was motivated by the question of how an atom radiates light as its electrons jump from excited states

Cherednikob and Van der Veken offer a systematic pedagogical introduction to the quantum field theory approach to the quantitative analysis of Wilson path-ordered exponentials in quantum chromodynamics and the applications of this formalism to the study of gauge-invariant quark and gluon correlation functions, which can be associated with the three-dimensional transverse momentum-dependent parton density functions, commonly known now as TMD pdfs or simple TMDs.
Quantum chromodynamics (QCD) is a physical theory that is a central part of our current most fundamental theoretical framework about matter.
Using the theory known as quantum chromodynamics (or QCD), the researchers were able to account for interactions between quarks and gluons--the subatomic inhabitants of protons and neutrons--in sufficient detail to show how those interactions generate the precise amount of mass that protons and neutrons possess.
He and others later constructed the quantum field theory of quarks and gluons called quantum chromodynamics, which seems to account for all the nuclear particles and their strong interactions.
The extreme "weakness" of this interaction implies that it is only experimentally accessible through the study of the measurement of small parity-odd interference effects amid the much larger effects of the strong interaction, described, described by quantum chromodynamics (QCD).
The Quantum Quark is a close look at quantum chromodynamics that does not require an extensive mathematics or physics background of the reader.
Quantum chromodynamics is the study of how quarks interact though the exchange of particles called gluons.
Johnson orders his story around the progression of theories and discoveries in quantum thinking, providing an extraordinary wealth of detail on such recondite topics as particle parity, mathematical renormalization, isospin, and quantum chromodynamics. He documents the contentions of postwar physics well and seems to possess a near omniscient sense of which researcher was thinking what in which year.
In this way, Gell-Mann founded the study of quantum chromodynamics, on the model of quantum electrodynamics, which had proved to work so well (see 1948).
The theory describing the dynamics of the fundamental particles called quarks is Quantum Chromodynamics (QCD).
QCD, or Quantum Chromodynamics, is the theory for the Strong force that binds together the fundamental particles, called quarks, to form protons and neutrons, as well as other hadrons.
The understanding of the formed nuclear matter is a main topic of the today's most theoretical and phenomenological models aimed to describe the conditions and to find the equation of state of the matter formed in heavy ion collisions at the LHC believed to be the quark-gluon plasma, predicted by the theory of strong interaction Quantum Chromodynamics (QCD) being currently under extensive development.
