Amplitudes 2016

Scattering amplitudes have played a central role in quantum field theory since its inception. Recent years have seen a remarkable advance in our understanding and in our ability to compute scattering amplitudes, both for theoretical and phenomenological purposes. At the peak of the Nordic summer, Nordita and Stockholm will serve as hosts for the international conference Amplitudes 2016. The conference is devoted to exciting developments in the field of scattering amplitudes and related subjects. This includes, but is not limited to: amplitudes in gauge, gravity, and string theories, AdS/CFT and integrability, integrand structure of SYM and supergravity, IR and UV behavior, mathematics of polylogarithms and integrals, Grassmannians and twistor string approaches, symmetries and soft theorems, and connections to LHC phenomenology.

      Asymptotic Uniqueness of The Veneziano Amplitude
      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.
