Color Randomization of Fast Gluon-Gluon Pairs in the Quark-Gluon Plasma [PDF]

Journal of Experimental and Theoretical Physics, 2019
We study the color randomization of two-gluon states produced after splitting of a primary fast gluon in the quark-gluon plasma. We find that for the LHC conditions the color randomization of the $gg$ pairs is rather slow. At jet energies $E=100$ and $500$ GeV, for typical jet path length in the plasma in central Pb+Pb collisions, the $SU(3)$-multiplet

Gluon-gluon interactions in the bag model [PDF]

Physical Review D, 1983
An effective spin-dependent interaction Hamiltonian for low-lying gluon modes is calculated to scrO(..cap alpha../sub s/) in the MIT bag model. We give expressions for the energy shifts of low-lying glueballs.

Triple (and quadruple) soft-gluon radiation in QCD hard scattering

Journal of High Energy Physics, 2020
We consider the radiation of three soft gluons in a generic process for multi- parton hard scattering in QCD. In the soft limit the corresponding scattering amplitude has a singular behaviour that is factorized and controlled by a colorful soft current ...

The ratio R = dσL/dσT in heavy-quark pair leptoproduction as a probe of linearly polarized gluons in unpolarized proton

Physics Letters B, 2018
We study the Callan–Gross ratio R=dσL/dσT in heavy-quark pair leptoproduction, lN→l′QQ¯X, as a probe of linearly polarized gluons inside unpolarized proton, where dσT (dσL) is the differential cross section of the γ⁎N→QQ¯X process initiated by a ...

Gluon TMD studies at EIC

EPJ Web of Conferences, 2016

How to measure the linear polarization of gluons in unpolarized proton using the heavy-quark pair leptoproduction

Physics Letters B, 2018
We study the azimuthal cos⁡φ and cos⁡2φ asymmetries in heavy-quark pair leptoproduction, lN→l′QQ¯X, as probes of linearly polarized gluons inside unpolarized proton, where the azimuth φ is the angle between the lepton scattering plane (l,l′) and the ...
