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

Leaders:

E.A. Strokovsky
E.S. Kokoulina

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

Scientific Programme:
Strangeness 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 ¹⁰B 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 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 yields in tne non-central deuteron-nuclei and 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 aimed on search of new resonances and verification of theoretical predictions about new phenomena in a dense nuclear matter.

Expected main results in 2015:

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 (E < 50 MeV) photon emission in deuteron-nuclei and 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) heavy nuclei with nuclei at the BM@N setup.
