In theoretical physics, quantum chromodynamics ( QCD) is the study of the strong interaction between quarks mediated by gluons. Quarks are fundamental particles that make up composite hadrons such as the proton, neutron and pion.
Learn about the theory that describes the strong force between quarks and gluons, the force-carrier particles of colour charge. Find out how QCD explains the short-range nature and confinement of the strong force, and the six flavours of quarks.
Learn about the strong force, quarks, gluons, color charge, and the history of QCD. Explore the particle zoo, the color field, and the Rutherford-style scattering experiments that led to the discovery of quarks.
Apr 16, 2024 · The theory describing how it works, called quantum chromodynamics, is so complicated we can’t use it to make direct calculations or precise predictions. One of the reasons for this complexity is...
A series of lectures on the basics of perturbative quantum chromodynamics and some applications to high-energy collisions. Learn about gauge invariance, Feynman rules, renormalization, running coupling, jets, DIS, W and Z production, and more.
Learn the basics of quantum chromodynamics (QCD), the theory of strong interactions, from quark model to perturbative QCD. The lectures cover topics such as factorization, evolution equations, and violations of Bjorken scaling.
Sep 22, 2022 · Learn how quantum chromodynamics (QCD) describes the strong force between quarks and how it produces the particle zoo of mesons and baryons. Explore the colour symmetry, the gluons, the confinement and the asymptotic freedom of QCD.
