The pion pole in hard exclusive vector-meson leptoproduction [PDF]
European Physical Journal A, 2014 Exploiting a set of generalized parton distributions (GPDs) derived from analyses of hard exclusive leptoproduction of ρ0, φ and π+ mesons, we investigate the ω spin density matrix elements (SDMEs) recently measured by the HERMES Collaboration.

Vector meson photoproduction studied in its radiative decay channel
, 2005 We provide an analysis of vector meson photoproduction in the channel of the vector meson decaying into a pseudoscalar meson plus a photon, i.e. $V\to P\gamma$.

Hidden gauge formalism for the radiative decays of axial-vector mesons [PDF]
, 2008 The radiative decay of the axial-vector resonances into a pseudoscalar meson and a photon is studied using the vector meson Lagrangian obtained from the hidden gauge symmetry (HGS) formalism.

Vector meson spectral function and dilepton production rate in a hot and dense medium within an effective QCD approach [PDF]
, 2014 A bstractThe properties of the vector meson current-current correlation function and its spectral representation are investigated in details with and without isoscalar-vector interaction within the framework of effective QCD approach, namely Nambu-Jona ...

Melting Spectral Functions of the Scalar and Vector Mesons in a Holographic QCD Model [PDF]
, 2009 We investigate the finite-temperature spectral functions of heavy quarkonia by using the soft-wall AdS/QCD model. We discuss the scalar, the pseudo-scalar, the vector, and the axial-vector mesons and compare their qualitative features of the melting ...

η′ → π0γγ and ��′ → ηγγ: a primer analysis
EPJ Web of Conferences, 2012 The electromagnetic rare decays η′ → π0γγ and η′ → π0γγ are analysed for the first time and their predicted branching ratios given. The vector meson exchange dominant contribution is treated using Vector Meson Dominance and the scalar component is ...

Nuclear shadowing at low Q^2 [PDF]
, 2003 We re-examine the role of vector meson dominance in nuclear shadowing at low Q^2. We find that models which incorporate both vector meson and partonic mechanisms are consistent with both the magnitude and the Q^2 slope of the shadowing data.Comment: 7 ...

Magnetic structure of vector mesons in lattice QCD
EPJ Web of Conferences, 2018 We have explored the response of the charged vector mesons on the external magnetic field. The g-factor of the charged vector ρ and K* mesons has been found.
