4 Nonsan06 - S.H.Lee 4 Relevant questions in J/  suppression  need to know J/  – parton dissociation c c c c 1.N cc – 10 pair in Au+Au at RHIC 2.T i > 300 MeV in RHICl 3.c+c  g g is very small 4.J/  is formed at 1.6 T c 5.  ’ is formed at T c 6.Dissociation effects 7.Recombination effect

5 Nonsan06 - S.H.Lee 5 2003: Asakawa and Hatsuda claimed J/  will survive up to 1.6 T c Quenched lattice calculation by Asakawa and Hatsuda using MEM T< 1.6 T c T> 1.6 T c J/  peak at 3.1 GeV J/  in Quark Gluon Plasma

6 Nonsan06 - S.H.Lee 6 Theoretical interpretations 1. C. H. Lee, G. Brown, M. Rho… : Deeply bound states 2. C. Y. Wong… : Deby screened potential  (GeV) 0 -0.8 Tc 1.6xTc J/  Binding energy as a function T J/  wave functions at finite T These will be used throughout this work But result is the same when is fixed

8 Nonsan06 - S.H.Lee 8 Basics in Heavy Quark system 1. Heavy quark propagation Perturbative treatment are possible because

9 Nonsan06 - S.H.Lee 9 2. System with two heavy quarks Perturbative treatment are possible when

10 Nonsan06 - S.H.Lee 10 q 2 process expansion parameter 0 Photo production of open charm -Q 2 < 0 QCD sum rules for heavy quarks m 2 J/  > 0 Dissociation cross section of bound states Perturbative treatment are possible when

11 Nonsan06 - S.H.Lee 11 Historical perspective on Quarkonium Haron interaction in QCD 1. Peskin (79), Bhanot and Peskin (79) a) From OPE b) Binding energy=  0 >>  2. Kharzeev and Satz (94,96), Arleo et.al.(02,04) a) Rederive, target mass correction b) Application to J/  physics in HIC

12 Nonsan06 - S.H.Lee 12 Rederivation of Peskin formula using Bethe-Salpeter equation (Lee,Oh 02) Resum Bound state by Bethe-Salpeter Equation

13 Nonsan06 - S.H.Lee 13 NR Power counting in Heavy bound state 1. Perturbative part 2. External interaction: OPE

14 Nonsan06 - S.H.Lee 14 LO Amplitude Increasing T

15 Nonsan06 - S.H.Lee 15 Not so large, however, LO QCD result is known to underestimate nucleon absorption cross section s 1/2 (GeV) Exp data from pA Oh, Kim,SHL 02

16 Nonsan06 - S.H.Lee 16 Moreover, in sQGP, strong coupling (g 2 ) effects are expected near Tc

17 Nonsan06 - S.H.Lee 17 NLO Amplitude

18 Nonsan06 - S.H.Lee 18 NLO Amplitude : 11 Collinear divergence when  1 =0. Cured by mass factroization

19 Nonsan06 - S.H.Lee 19 Mass factorization 11 Gluons whose kcos  1 < Q scale, should be included in parton distribution function Integration of transverse momentum from zero to scale Q 11

21 Nonsan06 - S.H.Lee 21 Total cross section for Upsilon by nucleon: NLO vs LO Large higher order corrections Even larger correction for charmonium NLO/LO

22 Nonsan06 - S.H.Lee 22 1. Large NLO correction near threshold, due to log terms 2. But at finite temperature, thermal masses will regulate the large correction Thermal quark and gluon masses of 300 MeV will Reduce the large correction Lessons from NLO calculation

23 Nonsan06 - S.H.Lee 23 NLO  +q  c+c+q NLO

24 Nonsan06 - S.H.Lee 24 NLO  +g  c+c+g NLO

25 Nonsan06 - S.H.Lee 25 Result and Summary 1.We showed that the process q(g)+J/   c+c+q(g) gives large thermal width (1 GeV) for J/  at 1.6 T c  Result depends of wave function or size 2.In heavy ion collision, as the initial QGP cools down, J/  will start forming at 1.6 T c. However, initially the dissociation from 3 body decay is very large.  J/  dissociation will become smaller only near T c
