  2. Introduction New strategic course of the JINR in particle physics & relativistic heavy ions is based on: - the development of the home accelerator facility NICA providing relativistic heavy ions & polarized beams - the relevant scientific program including: • Physics of relativistic heavy ions at MPD: study of various phases of strongly interacting matter & search for the mixed phase & critical end-point • Spin physics of low nucleon systems & nucleon spin structure (at NICA) • Flavour physics: check of the OZI rule study of exotic nuclei, search for multiquark states • Innovation projects: radiotherapy technologies, transmutation, etc. V.Kekelidze, JINR Scientific Council

  3. MPD 225 m IP2 Collider NICAcomplex allocation V.Kekelidze, JINR Scientific Council

  4. Physics motivation for relativistic heavy ions A study of hot & dense baryonic matter could provide relevant information on: • in-medium properties of hadrons & nuclear matter equation of state de-confinement and/or chiral symmetry restoration, - phase transition, mixed phase & critical end-point • the Early Universe evolution & formation of the neutron stars The MPD experiment is proposed to operate at NICA collider incollisions of heavy ion (over atomic mass range A = 1-238) by scanning of the energy regionSNN = 3-9 GeV V.Kekelidze, JINR Scientific Council

  5. Physics motivation for relativistic heavy ions The phase diagram in terms of the reduced energy density The evolution trajectories calculated with hybrid model • open markers: QGSM • filled markers: • evolution within • 3D relativistic hydrodynamics steps: 0.3 fm/c & 0.5 fm/c V.Kekelidze, JINR Scientific Council

  6. MPD experiment – first stage targets the effects to be studied on energy & centrality scanning: • Event-by-event fluctuation in hadron productions (multiplicity, Pt etc.) • HBT correlations indicating the space-time size of the systems involving π, K, p, Λ (possible changes close to the de-confinement point) • Directed & elliptic flows for various hadrons • Multi-strange hyperon production: yield & spectra (the probes of nuclear media phases) V.Kekelidze, JINR Scientific Council

  7. Competitiveness • Fixed target experiments NA61 at SPS CERN and CBM at SIS100/300 GSI • advantages of collider experiments: • possibility to have 4pacceptance ! • energy scan do not introduce significant variation on critical density of detected particles • Collider experiments running at high energies: STAR & Fenix at RHIC BNL, ALICE at LHC CERN • STAR plans to run at low energies (SNN = 4-9 GeV, for U92+) with limited luminocity (falls down) V.Kekelidze, JINR Scientific Council

  8. Operation mode Collider (pp,pd, p(d)A) fixed target (gaseuos) spp = (20+) GeV Spin physics atNICA new facility will provide intensive beams of polarized p,d (n) & different polarization of proton target • Intermediate energy (fixed target): • - ppelastic scattering (analyzing powers & correlation coefficients) • meson production in pp near the threshold • pd (3-nucleon forces, analyzing powers & correlation coefficients) • High energy (collider- IP2): • Transversity distribution (Drell-Yann & J/Ψ) • Spin transfer to hyperons V.Kekelidze, JINR Scientific Council
