Omega photoproduction beyond the resonance region at small u
A. Sibirtsev, K. Tsushima, S. Krewald
Within the meson exchange model we study meson photoproduction at energies above the s channel resonance region. Different model prescriptions for the vertex function a…
Distortions in the negative energy Dirac sea: violation of the Gottfried sum rule and in proton
K. Tsushima, A. W. Thomas, G. V. Dunne
We report on recent work concerning the effect which the change in vacuum structure (negative energy Dirac sea), in the presence of a confining scalar field, has on the nucleon str…
On the to ratio from proton-proton collisions
A. Sibirtsev, K. Tsushima, W. Cassing +1
We compare the recent COSY data on the total and cross sections with the predictions from two boson exchange models that either are based solely…
On the search for a narrow penta-quark Z baryon in NN interactions
M. V. Polyakov, A. Sibirtsev, K. Tsushima +2
The possibility for an observation of a narrow penta-quark baryon in reactions is discussed. It is shown that the reaction at excess energies around 100…
Study of Omega, Eta, Eta-prime and D-minus mesic nuclei
K. Tsushima
Using the quark-meson coupling (QMC) model, we investigate whether and mesons form meson-nucleus bound states. Our results suggest that one should expect to find $…
The role of the in the reaction
A. Sibirtsev, K. Tsushima, W. Cassing +1
Using the resonance model, which was successfully applied for the study of the reaction, we investigate reactions that should provide cleaner informatio…
