Quark and gluon relaxation in quark-gluon plasmas

Physical Review D, 1993
The quasiparticle decay rates for quarks and gluons in quark-gluon plasmas are calculated by solving the kinetic equation. Introducing an infrared cutoff to allow for nonperturbative effects, we evaluate the quasiparticle lifetime at momenta greater than the inverse Debye screening length to leading order in the coupling constant.

Hadronization of gluons in quark and gluon jets

Physical Review D, 1981
Fragmentation functions are calculated for quark and gluon jets decaying into mesons which couple substantially to two gluons. We then find a sizable increase for the eta'/..pi../sup 0/ ratio in a gluon jet as compared to a quark jet. This increase is a signature for the color content of Quantum Chromodynamics and a possible tool to isolate gluon jets.

Discovery of the gluon

AIP Conference Proceedings, 1994
The experimental discovery of the first Yang–Mills non-Abelian gauge particle — the gluon — in the spring of 1979 is summarized, together with some of the subsequent developments, including the role of the gluon in the recent discovery of the Higgs particle.

Colour gluons and scaling in a unified gauge model

Pramana - Journal of Physics, 1975
Deep inelastic weak and electromagnetic processes are considered within the parton framework taking the partons to be integrally charged quarks and coloured gluons.

Gluon-gluon fusion production mode.

2013
This Report summarizes the results of the activities in 2012 and the first half of 2013 of the LHC Higgs Cross Section Working Group. The main goal of the working group was to present the state of the art of Higgs Physics at the LHC, integrating all new results that have appeared in the last few years. This report follows the first working group report

Description of the gluon condensate

Physical Review D, 1986
We develop an effective Lagrangian for QCD in terms of order parameters of the gluon condensate. (A useful analogy to the Ginzburg-Landau theory of superconductivity may be made.) In this work the order parameters are identified with averages of the low-momentum components of the vector potential.

Gluon Condensation in Quark-Gluon Plasma

1985
According to the generally accepted view, at high enough temperature or/and density a transition may take place from the hadronic phase of the matter into the quark-gluon plasma phase.1, 2 We hope that in high energy heavy-ion collisions there is a chance to reach that region of physical conditions where this phase transition is possible.

The Gluon

2019
Abstract This chapter describes the description of the proton as a bound state of partons. After a review of the properties of parton distribution functions, it introduces the evidence for a component of the proton responsible for its binding.
