Model pluralism for logic

open access: yesNoûs, Volume 60, Issue 1, Page 136-160, March 2026.
Abstract It is well‐recognized in the sciences that a multitude of nonequivalent models are used by researchers to fulfill a range of goals, even for the same target system, a result known broadly as model pluralism. The possibility of the same form of pluralism occurring in logic, however, has not been adequately considered.

The Light-Cone Fock Expansion in Quantum Chromodynamics [PDF]

open access: yes, 2000
A fundamental question in QCD is the non-perturbative structure of hadrons at the amplitude level--not just the single-particle flavor, momentum, and helicity distributions of the quark constituents, but also the multi-quark, gluonic, and hidden-color ...

Galactic Cosmic Ray Ionization on Uranus; Geomagnetic Latitude Dependencies

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Galactic Cosmic Rays (GCRs) are a major source of atmospheric ionization, influencing ion abundance, aerosol formation, and electrical processes. GCR‐induced effects are expected to be more pronounced on Uranus than planets closer to the Sun for two reasons; reduced solar irradiance, and weaker solar modulation of incident GCR.

Chromomagnetism in nuclear matter

open access: yes, 2011
Quarks are color charged particles. Due to their motion there is a strong possibility of generation of color magnetic field. It is shown that however hadrons are color singlet particles they may have non-zero color magnetic moment.

On the influence of hadronic decay on the properties of hadrons

open access: yesZeitschrift für Physik C Particles and Fields, 1983
In a multichannel treatment of the\(q\bar q\)-system it is shown that the impact of decay on the spectra and wavefunctions of hadrons is substantial. Some consequences for potential models are worked out in detail. We conclude that an “equivalent” confining\(q\bar q\)-potential to be used in an effective single-channel treatment might deviate ...

Quantum GraviElectro Dynamics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

Twist analysis of the spin-orbit correlation in QCD

open access: yesJournal of High Energy Physics
We present a QCD analysis of the twist-three parton distribution functions associated with the spin-orbit correlation of quarks and gluons in spin- 1 2 $$ \frac{1}{2} $$ and spin-0 hadrons. We derive exact non-perturbative identities decomposing the spin-

Low Mass Scalar Mesons and Related Topics

open access: yes, 2007
We give a brief survey on the physical significance of the low-mass scalar mesons in QCD, and also report on recent lattice studies on the sigma and kappa mesons.

Assessing the Usefulness of Assurance Cases: Experience With the Large Hadron Collider

open access: yesSystems Engineering, Volume 29, Issue 1, Page 99-113, January 2026.
ABSTRACT Assurance cases (ACs) are structured arguments designed to show that a system is sufficiently reliable to function properly in its operational environment. They are mandated by safety standards and are largely used in industry to support risk management for systems; however, ACs often contain proprietary information and are not publicly ...

Measurement of ψ (2S) production as a function of charged-particle pseudorapidity density in pp collisions at s $$ \sqrt{s} $$ = 13 TeV and p–Pb collisions at s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 8.16 TeV with ALICE at the LHC

open access: yesJournal of High Energy Physics, 2023
Production of inclusive charmonia in pp collisions at center-of-mass energy of s $$ \sqrt{s} $$ = 13 TeV and p–Pb collisions at center-of-mass energy per nucleon pair of s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 8.16 TeV is studied as a function of charged ...
