Higgs phenomenon for higher spin fields on AdS_3

Understand

In a previous work, a marginal deformation of 2d coset type model with N=3 superconformal symmetry was studied, and it was interpreted as a change of boundary conditions for bulk fields in the dual higher spin theory.

• The deformation breaks generic higher spin gauge symmetry, and the generated mass of a spin 2 field was computed.
• The deformation might be related to the introduction of finite string tension in a superstring theory.
• In this paper, we extend the analysis and compute the masses of generic higher spin fields at the leading order of 1/c (c is the CFT central charge) but at the full order of the deformation parameter.
