26. Renewed look at η′ in medium

Youngshin Kwon

11/16/12, 1:30 PM

We revisit the question of whether the U_A(1) symmetry is effectively restored in hot and dense medium. In particular, by generalizing the Witten-Veneziano formula to finite temperature, we investigate whether the mass of η′-meson will change in medium due to the restoration of chiral symmetry.

40. Rho and Eta production in heavy ion collisions

Wei Dai (CCNU)

11/16/12, 1:55 PM

The large tansverse momentum specta of vector mesons such as Rho and Eta in Au+Au at 200 GeV and Pb+Pb collisions at 2.76 TeV are calculated within the NLO perturbative QCD improved parton model. We employed the broken SU(3) model to determine the quark and gluon fragmentation functions of octet vector mesons in a simple way with an SU(3) breaking parameter. And we are using the higher-twist...

46. Neutral pion measurements in Pb+Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV with ALICE at the LHC

Tomoya Tsuji (University of Tokyo (JP))

11/16/12, 2:20 PM

The theory of strong interactions, quantum chromodynamics (QCD), predicts a phase transition at high temperature. A new era in the study of QCD matter opened with the first collisions of Pb ions in November 2010 at the Large Hadron Collider (LHC) at CERN. Study of partonic energy loss is planned with high-pT neutral pion in a wide momentum range using the PHOton Spectrometer (PHOS) at the...
