Aspects of strings from higher spins

Shouvik Datta, ETH Zürich

The tensionless limit of string theory is described by a theory of gravity sourced by massless higher spins. In the context of holography, the relationship between these two theories can be sharpened further by studying how their CFT duals are related. The dual to AdS3 higher spin gravity is a coset CFT, while that for stringy gravity is a symmetric product orbifold CFT. In this talk, we show how states in the twisted sector of the orbifold CFT are reproduced from the primaries of the coset CFT. The crucial tool which facilitates this connection is the plane partition description of higher spin representations.
