Three-Loop Gluon Scattering in QCD and the Gluon Regge Trajectory
Physical Review Letters, 2022 We compute the three-loop helicity amplitudes for the scattering of four gluons in QCD. We employ projectors in the 't Hooft-Veltman scheme and construct the amplitudes from a minimal set of physical building blocks, which allows us to keep the computational complexity under control.

Quark and gluon relaxation in quark-gluon plasmas
Physical Review D, 1993The 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, 1981Fragmentation 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.

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.

Gluon-gluon fusion production mode.
2013This 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, 1986We 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
1985According 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.

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.

MASSIVE GLUONS AND QUARK GLUON PLASMA SIGNATURES
International Journal of Modern Physics E, 1992The evolution of the physical picture of the quark gluon plasma from an ideal gas to a complicated interacting system is reviewed. Recent calculations of quark gluon plasma signatures are discussed which consider a nonvanishing in-medium gluon mass.
