1. Why AdS/CFT for Nuclear Physics?Shear viscosity /entropy density
experiment: <0.1
for pQCD:
for String Theory : 1/4π =0.09
The method string theory used is AdS/CFT

Plan of the session:SJS : basic conceptsY. Kim: Bottom up Y. Seo: Top down K. Jo: Two point functions.
Aim of the talk is a communication: what can we do to-gether.
After I show a few pictures, I will just answer your questions.

HistoryBad for parton behaviorSo QCD string is good for low E
and bad for the high energy. Negative beta function of QCD
implied Asymptotic freedom. QCD string was dead in 1973.

Closed string 1974Found graviton in Closed string
Paradigm shift : alpha’ is changed from
1GeV to Plank scale.

D-braneDirichlett boundary condition D-brane = black p-brane with
charge. (Polchinski) Dp, Its vibration = open string modes closed string in warped geometry. If lambda>>1, gs<<1 Gravity description is valid.… too much constraint. Let go to
board.

What can we do with it. Phase transition, equation of state. Two point function
Transports. Spectral fct Viscosity conductivity heat cd
Elliptic flow(time dependence)Dissipation and energy loss. (drag-

ConclusionAlmost everything can be calcu-
lated in terms of ads/cft.Model dependence and deviation
from the real qcd is not controlled yet.
Can we bypass qcdhqcd v.s exp?
