Photoproduction of Scalar Mesons on Protons and Nuclei
نویسندگان
چکیده
We study the photoproduction of scalar mesons close to the threshold of f0(980) and a0(980) using a unitary chiral model. Peaks for both resonances show up in the invariant mass distributions of pairs of pseudoscalar mesons. A discussion is made on the photoproduction of these resonances in nuclei, which can shed light on their nature, a subject of continuous debate. PACS: 12.39.Fe, 13.60.Le, 25.20.Lj

Photoproduction of Quasi-bound Ω Mesons in Nuclei *
We propose the (γ, p) reaction as a means of producing possible quasi-bound states of ω mesons in nuclei. We use an effective Lagrangian, based on chiral SU (3) symmetry and vector meson dominance, in order to construct the ω-nuclear potential. The contribution of bound ω states is observable in the missing energy spectra of protons emitted in forward direction for several nuclei.
متن کاملTwo Pion Production in Photon Induced Reactions 3
Differences in the photoproduction of mesons on the free proton and on nuclei are expected to reveal changes in the properties of hadrons. Inclusive studies of nuclear photoabsorption have provided evidence of medium modifications. However, the results have not been explained in a model independent way. A deeper understanding of the situation is anticipated from a detailed experimental study of...
متن کاملPhotoproduction of quarkonium in proton-proton and nucleus-nucleus collisions.
We discuss the photoproduction of Upsilon and J/psi at high energy pp, pp, and heavy ion colliders. We predict large rates in pp interactions at the Fermilab Tevatron and in pp and heavy ion interactions at the CERN Large Hadron Collider. The J/psi is also produced copiously at the Relativistic Heavy Ion Collider. These reactions can be used to study the gluon distribution in protons and heavy ...
متن کاملIn-medium Properties of Hadrons
A diverse experimental program for the study of the photoproduction of mesons off nuclei has been carried out and is still running at the Mainz MAMI and Bonn ELSA electron accelerators with the TAPS, Crystal Barrel, and Crystal Ball calorimeters. It is motivated as a detailed study of the in-medium properties of hadrons and the meson nucleus interactions. Typical examples for the in-medium beha...
متن کاملThe Qcd Pomeron in Ultraperipheral Heavy Ion Collisions: Iv. Photonuclear Production of Vector Mesons
The photonuclear production of vector mesons in ultraperipheral heavy ion collisions is investigated within the QCD color dipole picture, with particular emphasis on the saturation model. The integrated cross section and the rapidity distribution for the AA → V AA (V = ρ, ω, φ, J/Ψ) process are computed and theoretical estimates for scattering on both light and heavy nuclei are given for energi...
