Higher spin algebras and large N=4 holography

Tuesday, 2 January, 2018

A new family of higher spin algebras that arises upon restricting matrix extensions of shs[λ] is found. We identify coset CFTs realising these symmetry algebras, and thus propose new higher spin-CFT dual pairs. These higher spin theories arise naturally as a subsector of string theory on AdS3×S3×S3×S1 for specific ratios of the radii of the two spheres.
