Summary of Lees Talk

• 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
T600 MeV _at_ 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.
