Photoproduction of η-mesons from light nuclei
In a series of experiments coherent and quasifree η-photoproduction from light nuclei (He, He, H) was investigated with the TAPS-detector at the Mainz MAMI-accelerator. The experiments were motivated by two different subjects: the determination of the isospin structure of the electromagnetic excitation of the S11(1535) resonance and the study of the η-nucleon and η-nucleus interaction at small ...
متن کاملInstantons and η Meson Production near threshold in NN collisions
An enhancement for the η production in proton-neutron collisions as compared with that in proton-proton scattering has been recently observed. We present a calculation for the production cross section, in proton-neutron collisions near threshold, within instanton model for the QCD vacuum and show that a specific flavor dependent nonperturbative quark-gluon interaction related to instantons is a...
متن کاملNear-Threshold η Meson Production in Proton–Proton Collisions
The production of η mesons has been measured in the proton-proton interaction close to the reaction threshold using the COSY-11 internal facility at the cooler synchrotron COSY. Total cross sections were determined for eight different excess energies (ǫ) in the range from ǫ = 0.5 MeV to ǫ = 5.4 MeV. The energy dependence of the total cross section is well described by the available phase–space ...
متن کاملRho-meson mass in light nuclei
The quark-meson coupling (QMC) model is applied to a study of the mass of the ρ-meson in helium and carbon nuclei. The average mass of a ρ-meson formed in 3,4He and C is expected to be around 730, 690 and 720 MeV, respectively.

متن کاملMeson Exchange Currents in Kaon Scattering on the Lightest Nuclei
The K + scattering on the lightest nuclei, d, 3 He and 4 He is studied in the framework of multiple scattering theory. Effects from MEC tied to the K + N → KN π reaction are evaluated. We found that at momentum transfers Q 2 < 0.5 (GeV/c) 2 contributions from MEC are much smaller than kaon rescattering corrections. This makes the conventional multiple scattering picture a reliable tool to study...
