Symmetries of the refined D1/D5 BPS spectrum
A bstract We examine the large N 1/4-BPS spectrum of the symmetric orbifold CFT Sym N ( M ) deformed to the supergravity point in moduli space for M = K 3 and T 4 . We consider refinement under both left- and right-moving SU(2) R symmetries of the superconformal …
