Omega photoproduction beyond the resonance region at small u

A. Sibirtsev, K. Tsushima, S. Krewald

Within the meson exchange model we study $ω$ meson photoproduction at energies above the s channel resonance region. Different model prescriptions for the $ω N N$ vertex function a…

On the $Λ$ to $Σ^{0}$ ratio from proton-proton collisions

A. Sibirtsev, K. Tsushima, W. Cassing +1

We compare the recent COSY data on the total $pp \to p Λ K^{+}$ and $pp \to p Σ^{0} K^{+}$ cross sections with the predictions from two boson exchange models that either are based solely…
