Priority:1
Status: In-progress

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:
Armenia, Azerbaijan, Bulgaria, Czech Republic, France, Germany, Poland, Russia, Slovakia, USA.

Scientific Programme:
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 main results in 2018:
  • The data on heavy ion and polarized proton-proton and polarized proton nucleus collisions taken in the STAR experiment at RHIC.

  • Beam energy measurement of transverse spin asymmetry in polarized pp collisions at energy 510 GeV and study of sign change in Sivers function.

  • 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.
