Extracting Kinetic Freeze‐Out Properties in High‐Energy Collisions Using a Multisource Thermal Model
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.We study the transverse momentum (pT) spectra of neutral pions and identified charged hadrons produced in proton–proton (pp), deuteron–gold (d–Au), and gold–gold (Au–Au) collisions at the center of mass energy sNN=200 GeV. The study is made in the framework of a multisource thermal model used in the partonic level.

Testing a conjecture on quantum chromodynamics
International Journal of Geometric Methods in Modern Physics, 2023 A Planck-scale model that includes quantum chromodynamics and goes beyond it, is tested against observations. The model is based on a single fundamental principle. Starting with Dirac’s proposal describing spin [Formula: see text] particles as tethered objects, quarks and elementary fermions are conjectured to be fluctuating rational tangles with ...

Chirally extended quantum chromodynamics
Nuclear Physics B - Proceedings Supplements, 1994 We propose an extended Quantum Chromodynamics (XQCD) Lagrangian in which the fermions are coupled to elementary scalar fields through a Yukawa coupling which preserves chiral invariance. Our principle motivation is to find a new lattice formulation for QCD which avoids the source of critical slowing down usually encountered as the bare quark mass is ...

Contemporary continuum QCD approaches to excited hadrons
EPJ Web of Conferences, 2016 Amongst the bound states produced by the strong interaction, radially excited meson and nucleon states offer an important phenomenological window into the long-range behavior of the coupling constant in Quantum Chromodynamics.

Chromoelectric flux tubes within non-Abelian Proca theory
European Physical Journal C: Particles and FieldsFlux tube solutions within non-Abelian SU(3) Proca theory with external sources are obtained. It is shown that such tubes have a longitudinal chromoelectric field possessing two components (nonlinear and gradient), as well as a transverse chromomagnetic ...

Polarization rotation of chiral fermions in vortical fluid
Physics Letters B, 2021 The rotation of polarization occurs for light interacting with chiral materials. It requires the light states with opposite chiralities interact differently with the materials.

Quantum simulation of quantum field theories as quantum chemistry
Journal of High Energy Physics, 2020 Conformal truncation is a powerful numerical method for solving generic strongly-coupled quantum field theories based on purely field-theoretic technics without introducing lattice regularization.
