AB  - As was recently found in [3], there exists a simple classical solution describing a closed string rotating in S<sup>5</sup> and located at the center of AdS<inf>5</inf>. It is parametrized by the angular momentum J of the center of mass and two equal SO(6) angular momenta J′ in the two other orthogonal rotation planes. The corresponding dual N = 4 SYM operators should be scalar operators in SU(4) representations [0, J - J′, 2J′] if J ≥ J′, or [J′-J, 0, J′+J] if J′ ≥ J. This solution is stable if J′ ≤ 3/2 J and for large J+2J′ its classical energy admits an expansion in positive powers of λ/(J+2J′)<sup>2</sup> (√λ is proportional to string tension): E = J + 2J′ +λ/(J+2J′)<sup>2</sup>J′ + . This suggests a possibility of a direct comparison with perturbative SYM results for the corresponding anomalous dimensions in the sector with λ/(J+2J′) <sup>2</sup>  1, by analogy with the BMN case. We conjecture that all quantum sigma model string corrections are then subleading at large J′, so that the classical formula for the energy is effectively exact to all orders in λ. It could then be interpolated to weak coupling, representing a prediction for the anomalous dimensions on the SYM side. We test this conjecture by computing the 1-loop superstring sigma model correction to the classical energy. © SISSA/ISAS 2003.

Note to staff:  Adding new publications to a research group

  1. Log in to Symplectic.
  2. Click on Menu > Create Links
  3. Choose what you want to create links between – in this case ‘Publications’ and ‘Organisational structures’.
  4. Choose the organisational structure (research group) into which you want to link the publications and check the box next to it.
  5. Now check the box of any publication you want to add to that group. You can use the filters to find what you want and select multiple publications if necessary. 
  6. Scroll to the bottom and click the blue ‘Create new link’ button to link them.
  7. The publications will be added to the group, and will be displayed on the group publications feed within 24 hours (it is not immediate).

Any problems, talk to Tim Evans or the Faculty Web Team.
