Charge symmetry breaking as a probe for he real part of eta nucleus scattering lengths
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 cross section ratio of pi(+) and pi(0) production on nuclei deviates from the isotopic value in the vicinity of the eta pr...

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 cross section ratio of pi(+) and pi(0) production on nuclei deviates from the isotopic value in the vicinity of the eta production threshold, due to, e.g., pi(0)-eta mixing, we argue that a systematic study of this ratio as a function of the energy would allow to pin down the sign of the real part of the eta-nucleus scattering length. This sign plays an important role in the context of the possible existence of eta-nucleus bound states. |
