Recent MILC spectrum results [PDF]
, 1996 We report on results from three spectrum calculations with staggered quarks: 1) a quenched calculation with the standard action for the gluons and quarks; 2) a quenched calculation with improved actions for both the gluons and quarks; and 3) a ...

Medium-induced gluon branching [PDF]
, 2012 We study the evolution of an energetic jet which radiates gluons while propagating through a dense QCD medium modeled as a random distribution of color sources.

Double-soft behavior for scalars and gluons from string theory [PDF]
, 2015 We compute the leading double-soft behavior for gluons and for the scalars obtained by dimensional reduction of a higher dimensional pure gauge theory, from the scattering amplitudes of gluons and scalars living in the world-volume of a Dp-brane of the ...

The two types of Cherenkov gluons at LHC energies [PDF]
, 2007 Beside comparatively low energy Cherenkov gluons observed at RHIC, there could be high energy gluons at LHC, related to the high energy region of positive real part of the forward scattering amplitude.

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 condensates and effective gluon mass
SciPost Physics, 2022 Lattice simulations along with studies in continuum QCD indicate that non-perturbative quantum fluctuations lead to an infrared regularisation of the gluon propagator in covariant gauges in the form of an effective mass-like behaviour. In the present work we propose an analytic understanding of this phenomenon in terms of gluon condensation through a ...

Physical Review D, 2005 In the strongly correlated environment of high-temperature cuprate superconductors, the spin and charge degrees of freedom of an electron seem to separate from each other. A similar phenomenon may be present in the strong coupling phase of Yang-Mills theories, where a separation between the color charge and the spin of a gluon could play a role in a ...

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 ...

Proton structure, its spin and tensor gluons
EPJ Web of Conferences, 2016 We assume that inside the hadrons there are additional partons - tensorgluons - which carry the same charges as the gluons, but have larger spin. That assumption leads to a possible contribution of polarised tensorgluon density to the spin of the nucleon.

Physics Letters B, 2018 We study the azimuthal cosφ and cos2φ 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 ...
