Thus far in the search for, and classification of, «physical» modular invariant partition functions ΣNLRχLxR* the attention has been focused on the symmetric case where the holomorphic and anti-holomorphic sectors, and hence the characters χL and χR, are associated with the same Kac-Moody algebras gL = gR and levels kL = kR. In this paper we consider the more general possibility where (gL, kL) may not equal (gR, kR). We discuss which choices of algebras and levels may correspond to well-defined conformal field theories, we find the «smallest» such heterotic (i.e. asymmetric) partition functions, and we give a method, generalizing the Roberts-Terao-Warner lattice method, for explicitly constructing many other modular invariants.
