The He scattering length revisited

A. Sibirtsev, J. Haidenbauer, C. Hanhart +1

The possible existence of -mesic nuclei poses an interesting and still open issue of research. Since the occurence of such -nucleus bound states is reflected in the correspon…

Pion-nucleon scattering in a meson-exchange model

A. M. Gasparyan, J. Haidenbauer, C. Hanhart +1

The pi-N interaction is studied within a meson-exchange model and in a coupled-channels approach which includes the channels pi-N, eta-N, as well as three effective pi-pi-N channel…

Investigating scalar meson mixing in nucleon--nucleon and deuteron--deuteron collisions

C. Hanhart

The advantages to study charge--symmetry breaking and especially the phenomenon of f0-a0 mixing in nucleon--nucleon and deuteron--deuteron induced reactions are discussed.

Angular asymmetries in the reactions pp \to dπ^+ηand pn \to dπ^0ηand a_0-f_0 mixing

A. E. Kudryavtsev, V. E. Tarasov, J. Haidenbauer +2

The reactions pp\to dπ^+ηand pn\to dπ^0ηare of special interest for investigating the a_0(980) (J^P=0^+) resonance in the process NN \to da_0 \to dπη. We study some aspects of thos…

Charge symmetry breaking as a probe for the real part of eta--nucleus scattering lengths

V. Baru, J. Haidenbauer, C. Hanhart +1

We demonstrate that one can use the occurrence of charge symmetry breaking as a tool to explore the eta--nucleus interaction near the eta threshold. Based on indications that the c…

An analysis of the reaction pp --> ppηnear threshold

K. Nakayama, J. Haidenbauer, C. Hanhart +1

It is shown that most of the available data on the reaction, including the invariant mass distributions in the reaction recently measured at COSY, can be un…
