  1. High pT suppression and v2 from PHENIX ShinIchi Esumi, Univ. of Tsukuba • Contents • High pT suppression • v2 and higher harmonics • HBT w.r.t. n • Jet correlation w.r.t. n ShinIchi Esumi, Univ. of Tsukuba

  2. (Non-) suppression of hadron (direct-photon) arXiv: 1208.2254 peripheral Au+Au central Au+Au arXiv: 1205.5759 - strong suppression of hadrons- no suppression of direct photons at high pT ShinIchi Esumi, Univ. of Tsukuba

  3. Thermal photons and their Flow d+Au arXiv: 1208.1234 arXiv: 1105.4126 Phys. Rev. Lett. 109, 122302 (2012) PHENIXQM12 Au+Au Au+Au - significant low pT photon excess - comparable v2 with hadrons ShinIchi Esumi, Univ. of Tsukuba

  4. Energy dependence of hadron suppression from low RHIC energy to LHC energy - smaller suppression (or enhancement) at low energy - saturation at high energy arXiv: 1204.1526 Phys. Rev. Lett.101, 162301 (2008) ShinIchi Esumi, Univ. of Tsukuba

  5. Fractional energy loss arXiv: 1204.1526 arXiv: 1208.2254 2.76 TeV 200 GeV - continuous increase of energy loss in terms of fractional energy loss in pT (coming from slope changes) ShinIchi Esumi, Univ. of Tsukuba

  6. RAA and v2 from RHIC to LHC - no simple solution to describe RAA and v2 for both RHIC/LHC simultaneously ShinIchi Esumi, Univ. of Tsukuba

  7. Phys. Rev. C 85, 064914 (2012) Deviation from nCQ scaling at 200GeV Au+Au - consequence of similar v2 at high pT for different particle species ShinIchi Esumi, Univ. of Tsukuba

  8. PHENIX, QM12 Central collisions (193GeV U+U) at RHIC - larger radial flow - various geometry tests on going with Cu+Au, U+U data from run12. ShinIchi Esumi, Univ. of Tsukuba

  9. PHENIX, QM12 Beam energy dependence for identified particle v2 and v3 - similar for all particle species ShinIchi Esumi, Univ. of Tsukuba

  10. Blast Wave fitting and nCQ scaling of identifiedparticle vn PHENIX, QM12 (a) : ~ v2 / nCQ (b) : ~ vn1/n (a)+(b) : ~ vn / nCQn/2 - anisotropy in velocity, coordinate - Tf and 0 constrained by spectra ShinIchi Esumi, Univ. of Tsukuba

  14. 2-part.  correlation with various flow subtraction (1) PHENIX, QM12 - v3 is largely responsible for away side “mach-cone” like shape ShinIchi Esumi, Univ. of Tsukuba

  15. 2-part.  correlation with various flow subtraction (2) - but v4{4} matters! PHENIX, QM12 ShinIchi Esumi, Univ. of Tsukuba

  16. PHENIX, QM12 mid-central - strong 2 dependence and left/right asymmetry coupling with geometry and/or expansion- almost no 3 dependence (poor 3 resolution) ShinIchi Esumi, Univ. of Tsukuba

  17. PHENIX, QM12 central - out-of-plane correlation enhanced (strong jet quenching and collective expansion)- some weak 3 dependence ShinIchi Esumi, Univ. of Tsukuba
