Résumé :
It is known that free classical fields of all spins together exhibit an infinite global symmetry which gives rise to an infinite set of conserved charges. We demonstrate that they can represent scattering amplitudes for lower-spin interacting quantum field theories. The proposed technique allows one to have a continuum of expressions leading to the same given amplitude, thus proposing a way to treat dualities between different approaches to amplitude calculations.
