These SDMEs give straightforward relations for understanding the nature of the parity exchange at threshold energies, as well as for extracting signatures of the Okubo-Zweig-Iizuka violation. Contrary to 3 Heneither a threshold enhancement of the total cross section nor a deviation of the angular distributions from the expected form factor dependence were observed.

K+Λ photoproduction provides the best possibility for a model independent extraction of the photoproduction process and contributing resonances. To do this, it is vital that cross section measurements are well understood. This thesis presents pγ K+Λ differential cross sections from the reaction threshold, to an invariant centre of mass energy of GeV. The data was taken at MAMI-C electron microtron facility in Mainz, Germany, during July and April The GeV MAMI-C electron beam was used to produce an energy tagged bremsstrahlung photon beam with a maximum energy of GeV and.

?-Meson Photoproduction with Linearly Polarized Photons at Threshold Energies. [Show abstract] [Hide abstract] ABSTRACT: The observables provided by linearly-polarized photons are of interest in delineating the contributions of the various hadronic processes giving rise to vector meson photoproduction.

In particular, we describe how phi-meson production affords an incisive tool for exploring the nature of the parity exchange at threshold energies, the strangeness content of proton, as well as extracting signatures for the violation of Okubo-Zweig-Iizuka observation (OZI rule).  Julian Salamanca Philip L.

Coherent photoproduction of π0-mesons from threshold (Eth ≈ MeV) throughout the Δ-resonance region and of η-mesons close to the production threshold (Eth ≈ MeV for η has been measured for 7Li nuclei.

The experiment was performed using the tagged-photon beam of the Mainz MAMI accelerator with the Crystal Ball and TAPS detectors combined to give an almost 4π solid-angle electromagnetic calorimeter. The reactions were identified by a combined invariant-mass and missing-energy analysis. A comparison of the pion data to plane-wave impulse modelling tests the nuclear mass form fact.

The parameters of six resonances of the isobar model for η′-meson photoproduction were fitted to experimental differential cross sections for the reaction γπ → η′p that weremeasured by the CLAS and CBELSA/TAPS Collaborations (Mainz, Germany). It was shown that, in the photon energy region from the reaction threshold to MeV, a good description of the experimental cross sections was attained by taking into account the contributions of high-angular-momenta heavy resonances alone.
