Abstract: (Elsevier)
We show that scattering amplitudes computed from light-cone superstring field theory are divergent at tree level. The divergences can be eliminated, and supersymmetry restored, by the addition of certain counter terms to the light-cone hamiltonian. These counter terms have the form of local contact interactions, whose existence we had previously deduced on grounds of vacuum stability and closure of the super-Poincaré algebra. The quartic contact interactions required in type I and type IIB superstring theories are constructed in detail.- MODEL: STRING
