Vector-meson production and vector meson dominance [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We consider the fidelity of the vector meson dominance (VMD) assumption as an instrument for relating the electromagnetic vector-meson production reaction $$e + p \rightarrow e^\prime + V + p$$ e + p → e ′ + V + p to the purely hadronic process $$V + p ...

Spin Information from Vector-Meson Decay in Photoproduction [PDF]

open access: green, 1998
For the photoproduction of vector mesons, all single and double spin observables involving vector meson two-body decays are defined consistently in the $\gamma N$ center of mass.

A chiral covariant approach to $$\varvec{\rho \rho }$$ ρ ρ scattering

open access: yesEuropean 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 dominance and the rho meson [PDF]

open access: yesPhysical Review D, 1998
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.

Vector Meson Dominance

open access: yes, 2005
Historically vector-meson physics arose along two different paths to be reviewed in Sections 1 and 2. In Section 3, the phenomenological consequences will be discussed with an emphasis on those aspects of the subject matter relevant in present-day ...

Light-Quark Vector Meson Spectroscopy [PDF]

open access: yesAIP Conference Proceedings, 2001
The current situation for vector meson spectroscopy is outlined, and it is shown that the data are inconsistent with the generally-accepted model for meson decay. A possible resolution in terms of exotic mesons is given.

Vector meson-vector meson interaction in a hidden gauge unitary approach [PDF]

open access: yesPhysical Review D, 2009
The formalism developed recently to study vector meson--vector meson interaction, and applied to the case of $\rho\rho$, is extended to study the interaction of the nonet of vector mesons among themselves. The interaction leads to poles of the scattering

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 ...
