  The Wen-Wu c=-2 model describes the d-wave paired singlet factor of the
Haldane-Rezayi (quantum Hall) wave function in terms of an SU(2) doublet of
dimension 1 fermions. The resulting CFT involves an infinite sequence of
Virasoro primary fields. The superalgebra generated by these fields, on the
other hand, admits a set of ground state representations giving rise to a
rational c=-2 CFT. We compute the corresponding characters as well as the
characters of the bosonic subalgebra in the Z_2 twisted sector and write down a
modular invariant partition function for the ensuing 2-dimensional conformal
theory.
