31. Measurement of $\Upsilon$ in $\mbox{p+p}$ collisions in the STAR experiment

Leszek Kosarzewski (Warsaw University of Technology)

Experimental

Quarkonium suppression was proposed as a signature of quark-gluon plasma(QGP) formation. Different members of the quarkonia family are expected to melt at different temperatures providing an estimate of the temperature reached in QGP. The $\Upsilon$ states offer a clean probe of QGP. Previous measurements at RHIC focused on colliding system and centrality dependence of $\Upsilon$ nuclear...

41. $J/\psi$ production in the Statistical Hadronization Model - limitations and implications

Mr Philipp Bahavar (Goethe University Frankfurt)

Theory

Using a Statistical Hadronization Model which includes charmed hadrons and charmonia, we describe thermal $J/\psi$ production on the hadronic as well as the partonic level under the assumption of detailed balance and entropy conservation. We investigate the dependence of the $J/\psi$ multiplicity on the primary model parameters, the freeze-out temperature and the baryochemical potential. We...

48. Inclusive J/ψ production in pp, p-Pb and Pb-Pb collisions at forward rapidity with ALICE at the LHC

Heavy flavor, dileptons and photons

Experimental

The ALICE collaboration has studied inclusive J/$\psi$ production in pp, p-Pb and Pb-Pb collisions with the ALICE Muon Spectrometer. The measurement was performed in the rapidity range 2.5 $<$ $y_{lab}$ $<$ 4.0, studying the decays into muon pairs. The J/$\psi$ production cross-sections in pp at $\sqrt{s}= 7$ TeV, both integrated and differential in rapidity and in transverse momentum will be...

46. Forward rapidity $\psi(\mathrm{2S})$ production in pp, p-Pb and Pb-Pb collisions with ALICE at the LHC

Marco Leoncino (University of Turin and INFN (IT))

27/09/2014, 18:30

Experimental

The ALICE Collaboration has studied the inclusive $\psi(\mathrm{2S})$ production in pp, p-Pb and Pb-Pb collisions at the CERN LHC. The $\psi(\mathrm{2S})$ is detected through its decay to muon pairs, using the Forward Dimuon Spectrometer, which covers the rapidity range 2.5<$y_{lab}$<4. The $\psi(\mathrm{2S})$ production cross sections in pp collisions will be presented, both integrated and...

74. $J/\psi$ production as a function of charged particle multiplicity in $p+p$ collisions at $\sqrt{s} = 510$ GeV

Mr Haiwang Yu (PKU, NMSU, LANL)

Experimental

In a high energy proton-proton collision, more than one inelastic parton-parton interaction can occur, which is described as multiple parton interaction (MPI). Each of the parton interaction would contribute to the overall particle multiplicity, as well as higher probability of producing a $J/\psi$ particle in the collision. Therefore, the MPI scenario can be tested by studying the yield of...
