Precision Test of AdS/CFT in Lunin-Maldacena Background

چکیده
We obtain the solutions and explicitly calculate the energy for a class of two-spin semiclassical string states in the Lunin-Maldacena background. These configurations are the β-deformed versions of the folded string solutions in AdS5 × S background. They correspond to certain single trace operators in the N = 1 superconformal β deformation of N = 4 Yang-Mills. We calculate the one loop anomalous dimension for the dual single trace operators from the associated twisted spin chain with a general two-cut distribution of Bethe roots. Our results show a striking match between the two calculations. We demonstrate the natural identification of parameters on the two sides of the analysis, and explain the significance of the Virasoro constraint associated with the winding motion of semiclassical strings from the perspective of the spin chain solution.

PREPRINT SERIES 2011 / 2012 NO : 2 TITLE : ‘ BRICK WALLS AND ADS / CFT ’ AUTHOR ( S ) : Dr
We discuss the relationship between the bulk-boundary correspondence in Rehren’s algebraic holography (and in other ‘fixed-background’, QFT-based, approaches to holography) and in mainstream string-theoretic ‘Maldacena AdS/CFT’. Especially, we contrast the understanding of black-hole entropy from the point of view of QFT in curved spacetime – in the framework of ’t Hooft’s ‘brick wall’ model – ...
متن کاملGravity duals to deformed SYM theories and Generalized Complex Geometry
We analyze the supersymmetry conditions for a class of SU(2) structure backgrounds of Type IIB supergravity, corresponding to a specific ansatz for the supersymmetry parameters. These backgrounds are relevant for the AdS/CFT correspondence since they are suitable to describe mass deformations or beta-deformations of four-dimensional superconformal gauge theories. Using Generalized Complex Geome...
متن کاملBlack Hole in Higher Curvature Gravity and AdS/CFT Correspondence
It is now well established that there exists the correspondence between the Supergravity theory on Anti-deSitter spacetime (AdS) and the Large N limit of Super Yang-Mills CFT. In the case of 3-d BTZ black hole , Strominger has given a simple statistical derivation of the Bekenstein-Hawking entropy via Cardy’s formula. This is an important check for the correspondence. The AdS/CFT correspondence...

A brief review is offered of employing Maldacena’s AdS/CFT correspondence in attempting to identify a model which extends to higher energy the standard model of particle phenomenology.
