Solving Schrödinger Wave Equation for the Charmonium Spectrum Using Artificial Neural Networks

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.
In this study, we solved the Schrödinger wave equation by using effective potential in an artificial neural network (ANN) for the mass spectrum of different charmonium states, including ηc, ψ2, χ2, and χ4. The ANN approach provides an efficient, more general, and continuous solution‐approximating strategy, thus eliminating the possibility of skipping ...

Pions in Large-$N$ Quantum Chromodynamics

, 2010
An effective field theory of quarks, gluons, and pions, with the number $N$ of colors treated as large, is proposed as a basis for calculations of hadronic phenomena at moderate energies.

High-energy limit of quantum electrodynamics beyond Sudakov approximation

Physics Letters B, 2015
We study the high-energy behavior of the scattering amplitudes in quantum electrodynamics beyond the leading order of the small electron mass expansion in the leading logarithmic approximation.

Quark Confinement Physics from Quantum Chromodynamics

, 2000
We show the construction of the dual superconducting theory for the confinement mechanism from QCD in the maximally abelian (MA) gauge using the lattice QCD Monte Carlo simulation.

Chromoelectric flux tubes within non-Abelian Proca theory

European Physical Journal C: Particles and Fields
Flux 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 ...

New tests of quantum mechanics with unstable nuclei

Physics Letters B
We propose and analyze two new tests of quantum mechanics that would probe the time evolution of unstable nuclei. The first is a search for a time-dependent nuclear magnetic moment in radioisotopes over several half-lives.

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.

K− over K+ multiplicity ratio for kaons produced in DIS with a large fraction of the virtual-photon energy

Physics Letters B, 2018
The K− over K+ multiplicity ratio is measured in deep-inelastic scattering, for the first time for kaons carrying a large fraction z of the virtual-photon energy.
