The gluon form factor to higher orders: Gluon-gluon annihilation at small Qt
Physics Letters B, 1988 Abstract We study the region of small transverse momenta in the dynamics of the gluon-gluon annihilation channel. This is done by evaluating the gluon form factor at the single non-leading infrared and collinear logarithmic accuracy to all orders in α s . An explicit expression for the gluon form factor is obtained.

Approximate Hamiltonian for baryons in heavy-flavor QCD
European Physical Journal C: Particles and Fields, 2018 Aiming at relativistic description of gluons in hadrons, the renormalization group procedure for effective particles (RGPEP) is applied to baryons in QCD of heavy quarks.

A look at hadronization via high multiplicity [PDF]
EPJ Web of Conferences, 2019 Multiparticle production is studied experimentally and theoretically in QCD that describes interactions in the language of quarks and gluons. In the experiment the real hadrons are registered.

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.

Light-cone singularities and transverse-momentum-dependent factorization at twist-3
Physics Letters B, 2017 We study transverse-momentum-dependent factorization at twist-3 for Drell–Yan processes. The factorization can be derived straightforwardly at leading order of αs.

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 ...

Higher-derivative relations between scalars and gluons
, 2023 We extend the covariant color-kinematics duality introduced by Cheung and Mangan to effective field theories. We focus in particular on relations between the effective field theories of gluons only and of gluons coupled to bi-adjoint scalars.

Coulomb gluons will generally destroy coherence
Journal of High Energy Physics, 2021 Coherence violation is an interesting and counter-intuitive phenomenon in QCD. We discuss the circumstances under which violation occurs in observables sensitive to soft radiation and arrive at the conclusion that almost all such observables at hadron ...

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.
