Production of eta mesons in nucleon-nucleon collisions
V. Baru, A. M. Gasparyan, J. Haidenbauer +3
A microscopic calculation of near-threshold eta-meson production in the reaction NN -> NNeta is presented. It is assumed that the eta meson is produced via direct emission and via…
Photoproduction of the Eta Meson from the Deuteron Near Threshold
Ch. Elster, A. Sibirtsev, S. Schneider +3
Very recent data for the reaction gamma{d} --> eta{np} are analyzed within a model that includes contributions from the impulse approximation and next order corrections due to the…
Pseudovector vs. pseudoscalar coupling in one-boson exchange NN potentials
G. Caia, J. W. Durso, Ch. Elster +3
We examine the effects of pseudoscalar and pseudovector coupling of the pi and eta mesons in one-boson exchange models of the NN interaction using two approaches: time-ordered pert…
Coherent photoproduction from nuclei and properties in nuclear matter
A. Sibirtsev, Ch. Elster, J. Speth
The coherent -meson photoproduction from nuclei is proposed as a phenomenological method to evaluate the momentum dependence of -meson mass shift and width in nuclear matter.…
Incoherent Eta Photoproduction from the Deuteron near Threshold
A. Sibirtsev, S. Schneider, Ch. Elster +3
Very recent data for the reaction gamma+d ->eta np, namely total cross sections, angular and momentum spectra, are analyzed within a model that includes contributions from the impu…
Aspects of a0-f0 mixing in the reaction pn->da0
A. E. Kudryavtsev, V. E. Tarasov, J. Haidenbauer +2
Some aspects of a0-f0 mixing effects in the reaction with perpendicular polarized proton beam are discussed. An angular--asymmetry parameter is defined t…
Eta Meson Production in NN Collisions
K. Nakayama, J. Speth, T. -S. H. Lee
Eta meson production in both proton-proton and proton-neutron collisions is investigated within a relativistic meson exchange model of hadronic interactions. It is found that the a…
