Title: Exploring the S-matrix of massless particles with a generalized BCFW recursion relation

Abstract: The BCFW construction for computing scattering amplitudes can be generalized to the case where the deformed amplitude has a bad complex-UV behavior. This new construction allows to study consistent theories at tree-level without any reference to a Lagrangian formulation. With this new approach, it is possible to rediscover the known interacting theories and their algebra from a pure S-matrix perspective. The analysis seems to leave room for high-spin interactions in flat space.
