Symmetries of the refined D1/D5 BPS spectrum
Abstract
We examine the large N 1/4BPS spectrum of the symmetric orbifold CFT Sym^{N} (M ) deformed to the supergravity point in moduli space for M = K3 and T ^{4}. We consider refinement under both left and rightmoving SU(2)_{R} symmetries of the superconformal algebra, and decompose the spectrum into characters of the algebra. We find that at large N the character decomposition satisfies an unusual property, in which the degeneracy only depends on a certain linear combination of left and rightmoving quantum numbers, suggesting deeper symmetry structure. Furthermore, we consider the action of discrete symmetry groups on these degeneracies, where certain subgroups of the Conway group are known to play a role. We also comment on the potential for larger discrete symmetry groups to appear in the large N limit.
