Search for η -mesic nuclei in the SRC/BM@N experiment at the Nuclotron

The SRC/BM@N experiment was carried out in the 55th run of the Nuclotron using a liquid hydrogen target and a carbon beam with a kinetic energy of about 3.1 GeV/n. We propose to analyze the experimental data to search for a quasi-bound state of η -meson and nucleons in the reaction 12 C+p → η (A-1)+...

Summary:The SRC/BM@N experiment was carried out in the 55th run of the Nuclotron using a liquid hydrogen target and a carbon beam with a kinetic energy of about 3.1 GeV/n. We propose to analyze the experimental data to search for a quasi-bound state of η -meson and nucleons in the reaction 12 C+p → η (A-1)+X → π +p+(A-2). To achieve this goal, it is necessary to identify the residual nucleus (A-2) and the proton-pion pair formed from η -nuclei decay.
