    Dissociation of heavy quarkonia is expected to happen in the quark-gluon plasma due to the Debye screening, which causes suppression of quarkonium yields in relativistic heavy ion collisions. Actually the $J/\psi$ suppression in SPS, RHIC and LHC as well as the sequential $\Upsilon$ suppression in LHC have been observed. However, since there are not only the medium effect but also other...

    The FASTSUM collaboration has been carrying out lattice simulations of QCD for temperatures ranging from one third to twice the critical temperature, investigating the chiral and deconfining aspects of the transition, as well as the properties of the Quark Gluon Plasma. In this contribution we concentrate on spectral functions and on some of the associated transport coefficients. We...

  3. 497. Measurements of Quarkonium Polarization and Production versus Charged-Particle Multiplicity in p+p Collisions at √s = 500 GeV in the STAR experiment

    Good knowledge of quarkonium production mechanism in p+p collisions is crucial for interpretation of the heavy-ion results. However, it is still not well understood after decades of effort. Simultaneous measurement of quarkonium spectrum and polarization in a wide kinematic range, notably at high transverse momentum, is suggested as a necessary step towards determination of quarkonium...

    A multi-dimensional analysis of charmonia in pp, pA, and AA collisions with the CMS detector will be presented. The prompt J/psi results are obtained using the $L_{int}=5.4 pb^{-1}$ pp, the $L_{int}= 35 nb^{-1}$ pPb, and the $L_{int}=150\mu b^{-1}$ PbPb data recorded between 2011 and 2013. The prompt J/psi nuclear modification factors ($R_{AA}$) and azimuthal anisotropy ($v_2$) in PbPb will be...
