Annalen der Physik, Volume 537, Issue 12, December 2025.A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

The Gluon Sivers Distribution: Status and Future Prospects
Advances in High Energy Physics, 2015 We review what is currently known about the gluon Sivers distribution and what are the opportunities to learn more about it. Because single transverse spin asymmetries in p↑p→πX provide only indirect information about the gluon Sivers function through ...

Two-Loop Gluon to Gluon-Gluon Splitting Amplitudes in QCD [PDF]
, 2004 Splitting amplitudes are universal functions governing the collinear behavior of scattering amplitudes for massless particles. We compute the two-loop g {yields} gg splitting amplitudes in QCD, N = 1, and N = 4 super-Yang-Mills theories, which describe the limits of two-loop n-point amplitudes where two gluon momenta become parallel.

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.

Radiation Transport Through the Martian Atmosphere as a Function of the Zenith Angle
Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.Abstract The topographic influence of the radiation environment on the Martian surface radiation is crucial for future human exploration. Topographic maps help assess radiation flux variations, aiding in hazard evaluation. Creating a global radiation map requires accounting for seasonally varying atmospheric density, heliospheric modulation, and ...

Sensitivity of the LHC to Kaluza-Klein gluon in two b-jets decay channel
EPJ Web of Conferences, 2013 We study a possibility of observation of the first Kaluza-Klein (KK) excitation of gluon in a warped extra dimension model at the LHC. In our analysis, we adopt the KK gluon mass and the b-quark coupling to the KK gluon as model parameters and study the ...

Physics Letters B, 1991 Abstract We calculate corrections to the electroproduction cross section of J/ψ at HERA energies arising from gluons in the photon interacting with gluons in the proton. These turn out to be sizable and may be isolated by suitable phase space cuts. Implications for the extraction of the gluon density of the proton at HERA are also discussed.

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract The production, attenuation, and absorption of secondary cosmic rays (SCR) are influenced by atmospheric parameters such as air pressure and temperature. To reliably correlate SCR flux measurements with atmospheric ionization driven by energetic particle precipitation, these dependencies must be quantified.

Shining a gluon beam through quark-gluon plasma
Physical Review D, 2012 We compute the energy density radiated by a quark undergoing circular motion in strongly coupled $\mathcal N = 4$ supersymmetric Yang-Mills plasma. If it were in vacuum, this quark would radiate a beam of strongly coupled radiation whose angular distribution has been characterized and is very similar to that of synchrotron radiation produced by an ...
