New strategic course of the JINR in relativistic heavy ions & particle physics endorsed by the PAC is based on:
- development of the home accelerator facility NICA providing relativistic heavy ions & polarized beams
- scientific programs at home & external accelerators including
a study of various phases of strongly interacting matter,urgent topics of particle physics and spin physics
Introduction
Relativistic Heavy Ion Physics is a high priority task in many
scientific centers (BNL, CERN, GSI, JINR,..) since last few decades
Theoretical motivation of relativistic heavy ion study reinforcementat JINR is well founded in the works of:
A.Sissakian, A.Sorin, V.Toneev, G.Zinoviev etc& others.

Heavy Ion Physics at SNN = 3-9 GeV
The phase diagram in terms of the reduced energy density
the trajectories are calculated with hybrid modelo open markers: QGSM
steps:0.3 fm/c & 0.5 fm/c
• filled markers:evolution within
3D relativistic hydrodynamics
SNN = 3-9 GeV is a most promising energy region
to search for mixed phase & critical end-point
