    Abstract

    In this paper we study three point functions of the type II superstring involving one graviton and two massive states, focusing in particular on the spin-7/2 fermions at the first mass level. Defining a gravitational quadrupole "h factor," we find that the nonminimal interactions of string states in general are parametrized by h ≠ 1, in contrast with the preferred field theory value of h = 1 (for tree-level unitarity). This difference arises from the fact that consistent gravitational interactions of strings are related to the presence of a complete tower of massive states, not present in the ordinary field theory case.
