Production of charged Higgs-boson pairs in gluon-gluon collisions [PDF]
Nuclear Physics B, 1998 The search for charged Higgs bosons, which are predicted in supersymmetric theories, is difficult at hadron colliders if the mass is large. In this paper we present the theoretical set-up for the production of charged Higgs boson pairs at the LHC in gluon-gluon collisions: $pp -> gg -> H^+ H^-$.

, 1980 1. The evidence from e+ e− collisions for QCD's gluons is considered. The criterion for a convincing experimental test is that plausible alternative scenarios fail to describe data.2.

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.

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.

Entanglement, partial set of measurements, and diagonality of the density matrix in the parton model
SciPost Physics Proceedings, 2022 To study quantum properties of the hadron wavefunction at small x, we derived the reduced density matrix for soft gluons in the CGC framework. We explicitly showed that the reduced density matrix is not diagonal in the particle number basis.

Work Versus Force: Simultaneous Processes for Describing Interactions
Advanced Physics Research, Volume 5, Issue 6, June 2026.ABSTRACT Achieving a unified description of interactions remains an open challenge in theoretical physics, which currently describes four fundamental forces. This situation may be viewed differently when interactions are formulated in terms of processes (work as actio) rather than forces (force as actio), not only at the macroscopic level but also at ...

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Spin-orbit entanglement in the Color Glass Condensate
Physics Letters BWe 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.

Fortschritte der Physik, Volume 74, Issue 1, January 2026.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.
