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

, 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.

Light vector mesons [PDF]

The European Physical Journal C, 2009
This article reviews the current status of experimental results obtained in the measurement of light vector mesons produced in proton-proton and heavy ion collisions at different energies. The review is focused on two phenomena related to the light vector mesons; the modification of the spectral shape in search of Chiral symmetry restoration and ...

Holographic picture of heavy vector meson melting [PDF]

The European Physical Journal C, 2016
The fraction of heavy vector mesons produced in a heavy ion collision, as compared to a proton–proton collision, serves as an important indication of the formation of a thermal medium, the quark–gluon plasma.

Color dipole predictions for the exclusive vector meson photoproduction in $pp$ , $pPb$ , and PbPb collisions at run 2 LHC energies [PDF]

, 2017
In this paper we present a comprehensive analysis of exclusive vector-meson photoproduction in pp, pPb and PbPb collisions at Run 2 LHC energies using the color dipole formalism. The rapidity distributions and total cross sections for the ρ, ϕ, J/Ψ, Ψ(2S)

Vector Meson Photoproduction with a Linearly Polarized Beam [PDF]

, 2018
We propose a model based on Reggae theory to describe photoproduction of light vector mesons. We fit the SLAC data and make predictions for the energy and momentum-transfer dependence of the spin-density matrix elements in photoproduction of omega, rho ...

$\eta \to \pi^0 \gamma \gamma$ decay within unitarized chiral perturbation theory [PDF]

, 2002
We improve the calculations of the $\eta \to \pi^0 \gamma \gamma$ decay within the context of meson chiral lagrangians. We use a chiral unitary approach for the meson-meson interaction, thus generating the $a_0(980)$ resonance and fixing the longstanding
