In 10-30 GeV energy heavy ion collisions (at the FAIR accelerator in Darmstadt and at NICA in Dubna will work at such energies) very dense - 6-10 times the normal nuclear density - matter is created. At these densities the matter is probably chiral symmetric. Its equation of state is very relevant for the investigation of neutron star properties. In this work an existing model should be developed further. New channels should be added.
