The QCD-vacuum is characterized by the Higgs phenomenon for colored scalar fields. In this dual picture the gluons appear as the octet of vector mesons. Also quarks and baryons are identified. Gluon-meson and quark-baryon duality can account in a simple way for realistic masses of all low-mass hadrons and for their interactions.

Abstract In this article I consider type II superstring in the pure spinor formulation with constant background fields in the context of T‐dualization. First, I prove that bosonic and fermionic T‐dualization commute using already known T‐dual transformation laws for bosonic and fermionic T‐dualization.

Thermalisation of Longitudinal Gluons
In the usual real-time finite-temperature gauge theory both the physical and the unphysical degrees of freedom are thermalised. We discuss the alternative approach where only the physical transverse components of the gauge field have bare thermal ...

Two-Loop Gluon to Gluon-Gluon Splitting Amplitudes in QCD [PDF]
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]
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.

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.

Spin-orbit entanglement in the Color Glass Condensate
We compute the spin-orbit correlations of quarks and gluons at small-x and show that the helicity and the orbital angular momentum of individual partons are strongly anti-aligned even in unpolarized or spinless hadrons and nuclei.

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.

Radiation Transport Through the Martian Atmosphere as a Function of the Zenith Angle
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 ...
