24 Jul 2008 | | Abstract: | We investigate conformal symmetries of the Aharony-Bergman-Jafferis-Maldacena
(ABJM) theory for multiple M2 branes and the Lorentzian
Bagger-Lambert-Gustavsson (L-BLG) theory which can be obtained by taking a
scaling limit k (>>N) -> infty of the ABJM theory. The conformal symmetry is
maintained in the L-BLG by considering general space-time varying solutions to
the constraint equations. The dual geometry is reduced to d=10 AdS4 x CP3 in
the scaling limit and has the same conformal symmetry. The curvature radius R
satisfies l_{11p} << l_{10p} << R << l_s (l_{dp} and l_s are the d-dimensional
Planck lengths and the string scale), and the theory is in a region where an
alpha’ expansion is not valid. We also study how the SO(8) covariance is
recovered in the AdS4 x CP3 geometry by taking the scaling limit. | | Source: | arXiv, 0807.3825 | | Services: | Forum | Review | PDF | Favorites | |
