Status: Being concluded

Investigation of the Properties of Nuclear Matter and Particle
Structure at the Collider of Relativistic Nuclei and Polarized Protons

Leaders:     R. Lednicky
Yu.A. Panebratsev

Participating countries and international organizations:
Azerbaijan, Bulgaria, Czech Republic, France, Germany, Poland, Russia, Slovakia, USA.

Issues addressed and main goals of research:
Investigation of the properties of nuclear matter with extremely high density and temperature, search for the signs of the quark deconfinement and possible phase transitions at the collisions of heavy nuclei at the energies of the Relativistic Heavy Ion Collider (RHIC). Measurement of spin dependent structure functions of nucleons and nuclei using polarized RHIC beams.

Expected results in the current year:
  • The data on beam energy scan at 19.6 GeV and 14.6 GeV.

  • The data of global polarization in gold-gold collisions.

  • Measurements of event structure, collective variables, correlation characteristics, femtosopic correlation functions and high PT processes.

  • Measurement of spin depended and gluon structure functions in polarized proton collisions with Al an Au nuclei.

  • Participation in JINR-BNL and JINR-CERN joint educational programs. Development of JINR educational portal.
