The techniques developed in a previous paper (I) to compute the T product 〈φNαβ(x), φNγδ(o)〉 for arbitrary N are extended to cover the case when φ(x) is a Hermitian matrix‐valued field in ν dimensions. We obtain a closed expression which is used to determine superpropagators like 〈[expκφ(x)]αβ, [expκφ(o)]γδ〉, which occur in strong interaction physics when φ is an SU(3) field, say.
