Parton distribution functions [PDF]

Nuclear Physics B - Proceedings Supplements, 1997
Parton distribution functions give the probability to find partons (quarks and gluons) in a hadron as a function of the fraction x of the proton's momentum carried by the parton. They are conventionally defined in terms of matrix elements of certain operators.

Two-particle correlation via Bremsstrahlung

EPJ Web of Conferences, 2017
Ridge is the well-known structure in two-particle angular correlations at highenergy heavy-ion collisions. This structure is physically understood through elliptic and higher-order flows at nucleus-nucleus collisions. This behavior is also found in small

Determination of parton densities for QCD partons and electroweak bosons

The European Physical Journal C
Abstract Parton densities are obtained from a solution of the extended DGLAP-type evolution equation that includes both QCD and electroweak contributions. The equations are solved using the Parton-Branching (PB) approach, and the evolution is performed at next-to-leading order for QCD partons and leading order for

MRST partons and uncertainties

, 2003
We discuss uncertainties in the extraction of parton distributions from global analyses of DIS and related data. We present conservative sets of partons, at both NLO and NNLO, which are stable to x,Q^2,W^2 cuts on the data. We give the corresponding values of alpha(M_Z^2) and the cross sections for W production at the Tevatron.

SPIKY STRINGS AND GAUGE THEORY PARTONS

, 2010
We propose a correspondence between strings with cusps which approach the boundary in AdS and energetic partons in the dual gauge theory on S3. In particular, the momenta of individual quanta on S3 are identified with certain collective coordinates ...

Scattering from an external field in quantum chromodynamics at high energies: From foundations to interdisciplinary connections

SciPost Physics Lecture Notes
We review the factorization of the $S$-matrix elements in the context of particle scattering off an external field, which can serve as a model for the field of a large nucleus.

La QCD et son histoire : partons d'un bon pied! [PDF]

, 2006
On présente d'abord très brièvement les modèles d'interactions fortes des années '60- '70. On décrit ensuite les differents ingrédients qui constituent ce qu'il est convenu d'appeler la Chromodynamique Quantique (QCD) perturbative : modèle des partons ...
