Heavy Vector Meson Production at Hera
Representing the H1 and ZEUS collaborations Recent results from the HERA experiments H1 and ZEUS on the exclusive production of heavy vector mesons V in ep collisions, i.e. the reaction ep ! eV p, are reviewed. The new measurements 1 include photoproduction of J== at larger photon-proton centre-of-mass energy W than previously, more precise data on J== electroproduction and (2S) photoproduction...
متن کاملVector meson dominance and the ρ meson
We discuss the properties of vector mesons, in particular the ρ 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. We then demonstrate the equivalence of HLS and the two existing re...
متن کاملDynamically generated resonances from vector meson-vector meson interaction based on a hidden-gauge unitary approach
We present a recent study of vector meson-vector meson interaction using a unitary approach based on the hidden-gauge Lagrangians. We find that 11 states get dynamically generated, corresponding to poles of the scattering matrices on the second Riemann sheet. Five of them are associated to the f0(1370), f0(1710), f2(1270), f ′ 2(1525), and K ∗ 2 (1430), by comparing the mass, width, and decay p...
متن کاملVector meson-vector meson interaction in a hidden gauge unitary approach
The formalism developed recently to study vector meson–vector meson interaction, and applied to the case of ρρ, 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. We show that 11 states (either bound or resonant) get dynamically generated in nine strangeness-iso...
