Strangeness in Hadronic Matter and Study of Inelastic Reactions Near Kinematical Borders

Leaders:     E.A. Strokovsky
E.S. Kokoulina

Participating Countries and International Organizations:
Belarus, Czech Republic, Germany, Japan, Russia, Ukraine.

Scientific Programme:
Srangeness in hadronic matter and study of boundary effects:
study of stabilizing effects of strangeness in nuclear matter and properties of the lightest hypernuclei;
study of multi-particle dynamics in inelastic proton-proton and proton-nucleus interactions with extremally high multiplicity;
study of spectra and yields of soft photons in deuteron-nucleus and nucleus-nucleus interactions.

Expected results:
  • Data on production cross sections for hyper-fragments of relativistic nuclei. Data on the lifetimes and binding energies of the lightest hypernuclei 4H,   3H,   6H;  search for 6H. Study of the decay channels, including non-mesonic decays of the 10Be   and 10 B hypernuclei.

  • New experimental data about the drip-line location for loosly bound light hypernuclei with high neutron excess. Development of theory of the neutron-rich hyper nuclei and models of their production in non-central nucleus-nucleus interactions.

  • New experimental data about soft photon emission in deuteron-nuclei and other nuclei-nuclei interactions, including study of dependence of their energy spectra on electric charges of the projectile and target nuclei, as well as on multiplicity of secondaries.

  • Development of theoretical and phenomenological models for description of data on the soft photon yield in tne deuteron-nuclei and other nuclei-nuclei iteractions, differentiated on multiplicity of secondaries.

  • Construction of two-arm electromagnetic calorimeter for soft photon registration in a wide region of emission angles for study of interference patterns, for search of new resonances and verification of theoretical predictions about new phenomena in a dense nuclear matter.
Expected main results in 2017:
  • Modernization of the FFE, DAQ and tracking systems of the NIS-GIBS spectrometer.

  • Data taking on the hyper-nuclear program (search for the hyper-hydrogen 6) using the NIS-GIBS spectrometer at extracted beams of deuterons and 7 nuclei.

  • Analysis of data from LEPS spectormeter on vector-meson photoproduction by polarized photons.

  • Analysis of data on soft (Egamma < 50 MeV) photon emission in deuteron-nuclei and other nuclei-nuclei interactions at kinetic energies above 2 GeV/nucleon.

  • Preparation of the NEMAN project aimed on study of photon emission in non-central collisions of relativistic (with kinetic energies above 1 GeV/nucleon) light and heavy nuclei with nuclei at the BM@N setup.
