1 Holography of Wilson-loop expectation values with local operator insertions Akitsugu Miwa ( Univ. of Tokyo, Komaba ) work in collaboration with Tamiaki Yoneya based on hep-th/0609007

2 introduction and motivation J.M.Maldacena(1997) AdS/CFT correspondence: present status and aim of this talk: generic loop: difficult circle, straight line: well studied small deformation of circle or straight line status this talk 4-dim, 4, SU(N), SYMIIB superstring on Wilson loop in AdS/CFT: S.J.Rey, J.Yee(1998), J.M. Maldacena(1998) Wilson loop string world sheet boundary AdS 5

3 deformation of loop and local operator insertion: Wilson loop: deformation of loop: large R-charge local operator insertions: N. Drukker S. Kawamoto (2006)

4 corresponding string world sheet: we consider:string world sheet with large angular momentum SO(6) symmetry: large R-charge gauge theory side R symmetry : SO(6): ( rotation of 6 scalars ) U(1) sub-group: rotation of a phase of string theory side isometry on S 5 : SO(6) U(1) sub-group: rotation in 5-6 plain 4 5 6

5 question: SYM side: string side:near boundaryseparated from boundary ? path of large angular momentum mode: classical path do not reach the boundary because of a potential barrier potential barrier path of large angular momentum mode

6 tunneling geodesic: S.Dobashi, H.Shimada, T.Yoneya (2002) we will study string world sheet around tunneling geodesic today’s talk: we want VEV of Wilson loop: path of localized angular momentum potential barrier tunneling solution correlation function of large R-charge local operators ex: 4 5 6

7 some comments string action: AdS/CFT correspondence: semi-classical approximation: large ‘t Hooft coupling in SYM semi-classical approximation of string theory requires large

8 plan of the talk introduction and motivation world sheet with large angular momentum evaluation of “area” of world sheets interpretation of results conclusion and future work

9 world sheet with large angular momentum S 5 part: solution: patch1 patch2 metric: path of localized angular momentum AdS 5 part: Hamiltonian constraint, EOM: boundary path of localized angular momentum

10 tunneling solution: S.Dobashi, H.Shimada, T.Yoneya (2002) tunneling solution (path of localized R-charge) world sheet we want: attached to a loop on the boundary propagating along the tunneling geodesic N.Drukker, S.Kawamoto (2006) comment on non-tunneling solution: If we use non-tunneling solution, it is difficult to check following relation:

11 full world-sheet solution: tunneling geodesic circle with radius

12 full world-sheet solution: corresponding Wilson loop:

13 evaluation of “area” of world sheets N.Drukker, D.Gross, H.Ooguri (1999) “area” of a world sheet two cutoff schemes target-space cutoff: world-sheet cutoff: w.s. cutoff can be rewritten as: divergences: singular behavior of the metric. infinite extension of the world sheet.

14 (const. depends on regularization schemes)results: consistent with ladder graph calculation

15 interpretation of results in our case consistent with our result ladder graph(planar graph without internal vertex): ladder graph (planar graph without internal vertex): D.Berenstein, R.Corrado, W. Fischler, J.M.Maldacena (1998), N.Drukker, D.J.Gross, H. Ooguri (1999), J.K.Erickson, G.W.Semenoff, K.Zarembo (2000), etc. not ladder circle: straight line: These results are known to be consistent with the calculation of the area of world sheet without angular momentum.

16 conclusion and future work future work: more complicated local operator insertions (more complicated deformation of string world sheet) conclusion: open string solution around the tunneling geodesic, the “area” of the world sheet in two cutoff schemes. We have studied Main results are ( consistent with ladder graph calculation ) and independent finite terms depend on cutoff schemes

17 Wilson loop in AdS/CFT S.J.Rey, J.Yee(1998); J.M.Maldacena(1998)conjecture: SYM side: Wilson loop string side: flat string world sheet

18 about Wilson loop localized R-charge

19 introduction and motivation J.M.Maldacena(1997) AdS/CFT correspondence: 4-dim, 4, SU(N), SYMIIB superstring on N D3-brane system flat boundary

20 present status and the aim of this talk: generic loop: difficult circle, straight line: well studied small deformation of circle or straight line status this talk Wilson loop in AdS/CFT: S.J.Rey, J.Yee(1998), J.M. Maldacena(1998) Wilson loop string world sheet boundary AdS 5 introduction and motivation
