Room: F2 (KTH Campus) We consider weakly coupled theories of massive higher spin particles. This class of models includes, for instance, tree-level String Theory and Large-N Yang-Mills theory. The S-matrix in such theories is a meromorphic function obeying unitarity and crossing symmetry. We discuss the (unphysical) regime s,t ≫ 1, in which we expect the amplitude to be universal and exponentially large. We develop methods to study this regime and show that the amplitude necessarily coincides with the Veneziano amplitude there. In particular, this implies that the leading Regge trajectory, j(t), is asymptotically linear in Yang-Mills theory. Further, our analysis shows that any such theory of higher spin particles has stringy excitations and infinitely many asymptotically parallel daughter trajectories. More generally, we argue that any weakly coupled theory with at least one higher spin particle must have strings.
