Stark effect and dissociation of mesons in holographic conductor
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.

RADIATIVE VECTOR MESON DECAY [PDF]
We study the radiative ρ, ω and ϕ decay into π0π0γ and π0ηγ taking into account mechanisms in which there are two sequential vector-vector-pseudoscalar or axial-vector–vector–pseudoscalar steps followed by the coupling of a vector meson to the photon, considering the final state interaction of the two mesons.

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 ...

Analysis of the b 1 meson decay in local tensor bilinear representation
We explore the validity of vector meson dominance in the radiative decay of the b 1(1235) meson. In order to explain the violation of the vector meson dominance hypothesis in this decay process, we investigate a model where the b 1 meson strongly couples

Vector meson and heavy meson strong interaction [PDF]
We calculate the coupling constants between the light vector mesons and heavy mesons within the framework of the light-cone QCD sum rule in the leading order of heavy quark effective theory. The sum rules are very stable with the variations of the Borel parameter and the continuum threshold.

QCD phase diagram with a background magnetic field in an improved soft-wall AdS/QCD model
We studied the magnetic effects on the chiral transition and the melting properties of vector and axial-vector mesons in the improved soft-wall AdS/QCD model under a charged magnetic background, which is solved perturbatively from an Einstein–Maxwell ...

Contribution of higher meson resonances to the electromagnetic $\pi$-meson mass difference [PDF]
Modifications of the DGMLY relation for calculation of electromagnetic $\pi$-meson mass difference based on the Chiral Symmetry Restoration phenomenon at high energies as well as the Operator Product Expansion of quark densities for vector ($\rho$) and ...

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