32 the study of hot & dense baryonic matter would provide us with relevant information on - in-medium properties of hadrons & nuclear matter equation of state - de-confinement and chiral symmetry restoration, - phase transition, mixed phase & critical end-point - possible strong P- & CP violation Physics motivation It is indicated in series of theoretical works -A. Sissakian, A. Sorin, V. Toneev, G. Zinovjev et al. -M. Gazdzicki, M. Gorenstein, -.... that an optimal way to reach the highest possible baryon density in the lab is heavy ion collision at S NN = 4 - 11 GeV/u 14 January 2010V.Kekelidze, PP PAC
