  • Are universal-process independent.

  • RG running of these operators - detailed tests of

Our model

model based on above physics + add valence quark contribution

Peeking through the Colored Looking Glass Quark-Deconfinement Nova model

A perspective on Future Directions?

Color Glass Condensate as Medium:

Pomerons, Odderons, Reggeons as Quasiparticle excitations of the CGC

-> ODD Couplerons develop: Larry, marrying with Klaus Werner??

Ploops: (Pomeron loops) How a little fluctuation becomes a big problem

The CGC and the QGP: Is the sQGP really the CGC? Is rapid “thermalization” due to the CGC? Does flow arise largely from the CGC?

Fluctuation studies Quark-Deconfinement Nova model


  • K/p fluctuations increase towards lower beam energy

    • Significant enhancement over hadronic cascade model

  • p/p fluctuations are negative

    • indicates a strong contribution from resonance decays

Summary of Lee’s Talk Quark-Deconfinement Nova model

  • Reported on the QCD NLO Quarkonium- Gluon/hadron dissociation cross section.

     Large correction even for upsilon system, especially near threshold

2. The corrections becomes smaller with thermal quark and gluon mass of larger than 200 MeV

 Thermal width of J/y : 1 GeV at T=600 [email protected] 1mb

3. The dissociation cross section due to quarks are less than 10 % of that due to the gluons.

 The quenched lattice calculation of the mass and width of J/y at finite temperature should be reliable.
