Parton particle
WebParton (particle physics) In particle physics, the parton model was proposed by Richard Feynman in 1969 as a way to analyze high-energy hadron collisions. [R.P. Feynman, Proceedings of the 3rd Topical Conference on High Energy Collision of Hadrons, Stony Brook, N. Y. (1969)] It was later recognized that partons describe the same objects now … http://www.scholarpedia.org/article/Introduction_to_Parton_Distribution_Functions

WebJan 1, 2024 · 2. Polarization rate for spin-1/2 particles In this note, we apply the result of Ref. [1] to calculate the global polarization in heavy ion collisions and compare it with the STAR data at √ sNN = 200 GeV [5]. We consider all 2-to-2 parton scattering processes A + B → 1 + 2 with at least one quark or anti-quark in the ï¬ nal state. WebThe color transparency (CT) of a hadron, propagating with reduced absorption in a nucleus, is a fundamental property of QCD (quantum chromodynamics) reflecting its internal structure and effective size when it is produced at high transverse momentum, Q. CT has been confirmed in many experiments, such as semi-exclusive hard electroproduction, …
WebJun 1, 1973 · The parton theory is developed along several lines. We begin by developing quantum mechanics in the infinite momentum frame. The Galilean analogy is worked out … WebMay 4, 2012 · The term parton now means any particle inside a proton, neutron or other quark-containing particle. By far, quarks and gluons are the most common partons. While up, down and strange quarks were components of the original model, we have since found three others, called charm, bottom and top. Both the bottom and top quarks were …
WebMay 14, 2024 · A parton distribution function within so called collinear factorization is defined as the probability density for finding a particle with a certain longitudinal momentum fraction x at resolution scale Q2. Because of the inherent non-perturbative nature of partons which cannot be observed as free particles, parton densities cannot be calculated ...
