Vector meson dominance and the ρ meson [PDF]
Physical 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.

QCD description of backward vector meson hard electroproduction [PDF]
, 2015 We consider backward vector meson exclusive electroproduction off nucleons in the framework of collinear QCD factorization. Nucleon to vector meson transition distribution amplitudes arise as building blocks for the corresponding factorized amplitudes ...

A chiral covariant approach to $$\varvec{\rho \rho }$$ ρ ρ scattering
European Physical Journal C: Particles and Fields, 2017 We analyze vector meson–vector meson scattering in a unitarized chiral theory based on a chiral covariant framework restricted to $$\rho \rho $$ ρ ρ intermediate states.

Vector meson-vector meson interaction in a hidden gauge unitary approach [PDF]
Physical Review D, 2009 The formalism developed recently to study vector meson--vector meson interaction, and applied to the case of $ $, is extended to study the interaction of the nonet of vector mesons among themselves. The interaction leads to poles of the scattering matrix corresponding to bound states or resonances.

Using coherent dipion photoproduction to image gold nuclei
SciPost 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]
EPJ 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 ...

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