Interactions in new string theories
Journal article, 1986

Couplings are introduced in the recently proposed non-supersymmetric string theories containing fermions. Both the conformal/Lorentz invariance and the gravity content imply a two-derivative structure. The pomeron singularity is a pole. The structure of loop amplitudes is briefly discussed.
