Relativistic corrections to the vector meson light front wave function [PDF]

open access: yesPhysical Review D, 2020
We compute a light front wave function for heavy vector mesons based on long distance matrix elements constrained by decay width analyses in the Non Relativistic QCD framework.

Using coherent dipion photoproduction to image gold nuclei

open access: yesSciPost Physics Proceedings, 2022
Vector meson photoproduction offers the opportunity to image target nuclei. The two-dimensional Fourier transform $d\sigma_{\rm coherent}/dt$ of coherent vector meson photoproduction gives the two-dimensional distribution of interaction sites in the ...

There is only one set of the correct values of fF, fD and fS coupling constants in SU(3) invariant Lagrangian of the vector-meson-baryon interactions [PDF]

open access: yesEPJ Web of Conferences, 2019
One can prove, there is generally eight various ω − ø mixings forms in elementary particle physics, which on one side give different forms of the vector-meson-nucleon coupling constants through fF, fD and fS in SU(3) invariant Lagrangian of the vector ...

Vector meson dominance and the ρ meson [PDF]

open access: yesPhysical Review D, 1999
We discuss the properties of vector mesons, in particular the rho^0, in the context of the Hidden Local Symmetry (HLS) model. This provides a unified framework to study several aspects of the low energy QCD sector. Firstly, we show that in the HLS model the physical photon is massless, without requiring off field diagonalization.

Electromagnetic form factors of Λ hyperon in the vector meson dominance model [PDF]

open access: yesPhysical Review D, 2019
We perform an analysis on the electromagnetic form factors of the $\Lambda$ hyperon in the time-like reaction $e^+e^-\rightarrow \Lambda\bar\Lambda$ by using a modified vector meson dominance model. We consider both the intrinsic structure components and

Exclusive vector meson production at an electron-ion collider [PDF]

open access: yesPhysical Review C, 2018
Coherent exclusive vector meson electroproduction is a key physics channel at an electron-ion collider. It probes the gluon structure of nuclei over a wide range of $Q^2$, and can be used to measure nuclear shadowing and to search for gluon saturation ...

Stark effect and dissociation of mesons in holographic conductor

open access: yesJournal of High Energy Physics, 2023
We study the meson spectrum of the N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory with N $$ \mathcal{N} $$ = 2 fundamental hypermultiplets for a finite electric field by using the D3/D7 model.

Exclusive vector meson production in heavy ion collisions [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2019
We discuss the salient features of exclusive vector meson production in heavy ion collisions at LHC energies. Special attention is paid to the space-time picture of the process. We account for both coherent and incoherent contributions.

Vector mesons in medium [PDF]

open access: yesAAPPS Bulletin, 2021
AbstractAfter decades-long attempts to measure the mass shift and understand the origin of hadron mass, it became clear that one has to analyze hadrons with small vacuum width. Also, to identify the effect of chiral symmetry breaking, one has to start by looking at chiral partners.
