Quantum‐Classical Simulation of Quantum Field Theory by Quantum Circuit Learning

Annalen der Physik, Volume 537, Issue 6, June 2025.
Quantum circuit learning is employed to simulate quantum field theories (QFTs). By integrating a minimal qubit configuration and low‐depth circuits, the approach predicts real‐time dynamics accurately. It effectively simulates complex phenomena such as quench and chiral dynamics in a model of quantum electrodynamics, aligning well with classical ...

T-odd transverse momentum dependent gluon fragmentation functions in a spectator model

Physics Letters B
We present a model calculation of the T-odd transverse momentum dependent (TMD) gluon fragmentation functions for a spin-1/2 hadron. Our model is based on the postulation that a time-like off-shell gluon can fragment into a hadron and a single spectator ...

Charm photoproduction at HERA: kt-factorization versus experimental data

, 2006
We calculate the cross section of charm photoproduction at HERA collider in the framework of the kt-factorization QCD approach. Our analysis cover the inclusive charm production as well as charm and associated jet production processes.

Automation of Predictive Maintenance: An Experimental Framework for Aircraft Landing Gear

Engineering Reports, Volume 7, Issue 6, June 2025.
Modern aircraft generate vast flight data, yet limited domain expertise hinders widespread predictive maintenance model development. This study compares traditional and automated machine learning (AutoML) models for Airbus landing gear health monitoring, showing AutoML's potential to streamline workflow, improve accessibility, and enable non‐experts to

Glueball spectrum based on a rigorous three-dimensional relativistic equation for two-gluon bound states I: Derivation of the relativistic equation

, 2004
A rigorous three-dimensional relativistic equation satisfied by two-gluon bound states is derived from the QCD with massive gluons. With the gluon fields and the quark fields being expanded in terms of the gluon multipole fields and the spherical Dirac ...

Soft-gluon factorization and multi-gluon amplitude

Nuclear Physics B, 1988
Abstract The infrared analysis of perturbative QCD starts from the formula of factorization of the soft-gluon radiation, which has the form of a semi-classical non-abelian current. This formula has been proved within the framework of the old-fashioned perturbation theory but no general proof is available in the more familiar framework of the Feynman ...

Neutrinoloser Doppelbetazerfall: Der Gral der Neutrinophysik

Physik in unserer Zeit, Volume 56, Issue 3, Page 132-137, May 2025.
Die Entschlüsselung der Neutrinoeigenschaften ist auch siebzig Jahre nach ihrer Entdeckung noch nicht abgeschlossen. Es wäre eine spektakuläre Entdeckung, sollten Neutrinos ihre eigenen Antiteilchen sein und sich folglich als Majorana‐Teilchen entpuppen. Mehrere Experimente untersuchen diese Möglichkeit.

Extraction of gluon distributions from structure functions at small x in holographic QCD

Physics Letters B, 2020
We investigate the nucleon and pion gluon distribution functions in the framework of holographic QCD, focusing on the small Bjorken x region. Based on an approximate relation, the gluon distributions are extracted from structure functions of the ...

An Algebraic Roadmap of Particle Theories

Annalen der Physik, Volume 537, Issue 4, April 2025.
The SO(10) grand unified theory, the Georgi–Glashow SU(5) grand unified theory, the Pati–Salam model, the Left–Right Symmetric model, and the Standard model have been studied extensively since the 1970s. Recasting these models in a division algebraic language elucidates how they are each in fact connected.
