Bound States of Little Strings and Symmetric Orbifold CFTs

Abstract

We study BPS bound states of little strings in a limit where they realise monopole strings in five dimensional gauge theories. The latter have gauge group $U(M{)}^N$ and arise from compactification of $(1,0)$ little string theories of type $A_{M-1}\times A_{N-1}$. We find evidence that the partition function of a certain subclass of monopole strings of charge $(k,\dots ,k)$ ($k\ge 1$) is expressible as the partition function of a symmetric orbifold sigma model, whose target space is precisely the symmetric product of the moduli space of monopoles with charge $(1,\dots ,1)$.
