Description
In $AdS_3/CFT_2$, the gravity sector includes not only supergravitons but also states involving singletons. In our previous work, we studied the construction of this gravity sector in the D1-D5 CFT at $N=2$. In this talk, we extend the analysis to general $N$. We also investigate the lifting of BPS states under deformations away from the free orbifold point. This talk is based on ongoing work with Marcel R. R. Hughes, Daiki Matsumoto, and Masaki Shigemori.
