Priority:

Status:

In-progress

Investigation of the Properties of Nuclear Matter in Experiments with Nuclei and Polarized Particles
(Projects DISK, STAR, CERES/NA45)

Leader:

Yu.A. Panebratsev

Scientific Programme:
Investigation of the asymptotic properties of extremely excited nuclear matter and vacuum nature of the quantum field theory in experiments at the relativistic nuclei and polarized proton collider RHIC. Study of the hot early stage of the dynamics of ultrarelativistic nuclear collisions in the experiment CERES/NA45 dedicated to the measurement of electron-positron pairs and direct photons at CERN SPS energies. Study of the properties of polarized and nonpolarized nuclear matter at small distances in experiments on cumulative and high P_T particle production (the DISK spectrometer).

Expected main results in 2004:

Manufacture and assembling of the End Cap EMC for ther STAR experiment at RHIC.
Data taking and analysis of experimental data on gold-gold collisions from the STAR experiment at RHIC.
Analysis of the experimental data on electron-positron pair production in lead-gold collisions at 40, 80 and 160 GeV with high resolution on the effective mass accumulated in the lead beam runs at SPS with the upgraded CERES/NA45 spectrometer.
Manufacturing and tests of elements of the silicon vertex detector for the DISK experiment at the Nuclotron.
