Marginal deformations and the Higgs phenomenon in higher spin AdS_3 holography

Understand

Recently, a 2d coset model with N=3 superconformal symmetry was proposed to be holographic dual to a higher spin supergravity on AdS_3 and the relation to superstring theory was discussed.

• However, away from the tensionless limit, there is no higher spin symmetry and the higher spin states are massive.
• In this paper, we examine the deformations of the coset model which preserve N=3 superconformal symmetry, but break generic higher spin symmetry.
• We focus on double-trace type deformations which are dual to changes of boundary conditions for the bulk matter fields.
