  1. Strong Magnetic Fields in HIC V. Toneev In collaboration withE. Bratkovskaya, W. Cassing, V. Konchakovski, S. VoloshinV. Voronyuk ♥Lecture 1. Collective Properties of Heavy Ion Collisions within Non-equilibrium Dynamics ♥Lecture 2.Evolution of the Electromagnetic Field in HIC and Chiral Magnetic Effect August 28 - September 8, 2012, Dubna, Helmholtz International SchoolDense Matter in Heavy-Ion Collisions and Astrophysics

  2. Lecture 1. Collective Properties of Heavy Ion Collisions within Non-equilibrium Dynamics ♥Parton Hadron-String Dynamics Model ♥ Flows in Heavy Ion Collisions from AGS to RHIC energy range

  3. Parton-Hadron String Dynamics: Goul and main ingredients

  4. The dynamical quasiparticlemodel (DQPM) Entropy density in the quasiparticle limit Bose and Fermi distribution functions Quasiparticle propogators Self energies

  5. Off-shell elements in the DQPM

  6. Thermodynamics => transport approach Parton density (DQPM)

  7. Boltzmann equation -> off-shell transport see D.Voskresensky’s lectures

  8. PHSD: hadronization

  9. PHSD: hadronization

  10. Hadronization details

  11. PHSD - summarizing

  12. Expanding fireball

  13. Global obsrvables: rapidity spectra of π-, K+ and K-at SPS

  14. Transverse momentum spectra at SPS

  15. Rapidity spectra at RHIC

  16. Transverse mass spectra at RHIC

  17. M.Nasim et al.,, PR C82, 054908 (2010) Neither hadronic nor partonic models can explain the energy dependence of v2 ! Energy dependence of v Flow harmonics Almond-like interaction zone ? pressure gradient => spatial asymmetry is converted to an asymmetry in momentum space => collective flow Direct flow Elliptic flow

  18. Event plane angle fluctuation Au+Au (200 GeV); b=10 fm Distribution of odd harmonics is practically flat in 0<Ѱn<2π/n; even harmonics are picked at zero. There is no “tilting” effect due to EM field V.Konchakovski et al., PR C85, 044922 (2012)

  19. v2 is reasonably described by PHSD due to an increasing fraction of partonic degrees of freedom ! V.Konchakovski et al., PR C85, 044922 (2012)

  20. Time evolution of vn (early time formation) V.Konchakovski et al., PR C85, 044922 (2012)

  21. V.Konchakovski et al., PR C85, 044922 (2012)

  22. “universal” scaling approximately works in PHSD but fails in hydrodynamics V.Konchakovski et al., PR C85, 044922 (2012)

  23. Scaling in pseudo-rapidity Longitudinal scaling approximately works in PHSD V.Konchakovski et al., PR C85, 044922 (2012)

  24. V.Konchakovski et al., PR C85, 044922 (2012)

  25. V.Konchakovski et al., PR C85, 044922 (2012)

  26. Not compatible with ideal hydrodynamics and very sensitive to the microscopic dynamics V.Konchakovski et al., PR C85, 044922 (2012)

  27. A. Peshier, W. Cassing, PRL 94, 172301 (2005)
