Abstract We explore the OPE of certain twist operators in symmetric product (S N ) orbifold CFTs, extending our previous work [1] to the case of N $$ \mathcal{N} $$ = (4, 4) supersymmetry. We consider a class of twist operators related to the chiral primaries by spectral flow parallel to the twist. We conjecture that at large N, the OPE of two such operators contains only fields in this class, along with excitations by fractional modes of the superconformal currents. We provide evidence for this by studying the coincidence limits of two 4-point functions to several non-trivial orders. We show how the fractional excitations of the twist operators in our restricted class fully reproduce the crossing channels appearing in the coincidence limits of the 4-point functions. |
