Search for η-mesic states at BGO-OD — •Eric Gutz — II. Physikalisches Institut, Justus-Liebig-Universität Gießen

The study of the interaction between mesons and the nuclear medium is a very promising approach to understand strong QCD at a fundamental level. The determination of the real and imaginary part of the η-nucleus potential [1,2] indicates attraction and a relatively narrow in-medium width of the η meson, making it a suitable candidate for the observation of meson-nucleus bound states. It has been proposed [3] to search such states in the 12C(γ,p) η11B reaction, using the BGO-OD setup at ELSA which combines a magnetic spectrometer at forward angles with photon detection over a large solid angle in the BGO ball. This setup allows a search for η mesic states by missing mass spectrometry as well as by looking for decays from η mesic states in coincidence with forward going protons. Simulations of the proposed reaction will be presented and the feasibility of the experiment will be discussed in view of a recent test experiment.
