“…Moreover, the spin 3 self interaction requires structure constants like those in spin 1 self interactions. Results in the light-front gauge [3,4] confirm and extend the pattern of the table: d = s 1 − 1 (s 1 ≥ s 2 ) and d = 2s 2 − s 1 − 1 (s 1 ≤ s 2 ). Structure constants are required for all odd spin self interactions.…”

In this paper the general form of scattering amplitudes for massless particles with equal spins s (ss → ss) or unequal spins (s a s b → s a s b ) are derived. The imposed conditions are that the amplitudes should have the lowest possible dimension, have propagators of dimension m −2 , and obey gauge invariance. It is shown that the number of momenta required for amplitudes involving particles with s > 2 is higher than the number implied by 3-vertices for higher spin particles derived in the literature. Therefore, the dimension of the coupling constants following from the latter 3-vertices has a smaller power of an inverse mass than our results imply. Consequently, the 3-vertices in the literature cannot be the first interaction terms of a gauge-invariant theory. When no spins s > 2 are present in the process the known QCD, QED or (super) gravity amplitudes are obtained from the above general amplitudes.

Light-cone gauge formulation of relativistic dynamics of a continuous-spin field propagating in the flat space is developed. Cubic interaction vertices of continuous-spin massless fields and totally symmetric arbitrary spin massive fields are studied. We consider parity invariant cubic vertices that involve one continuous-spin massless field and two arbitrary spin massive fields and parity invariant cubic vertices that involve two continuousspin massless fields and one arbitrary spin massive field. We construct the complete list of such vertices explicitly. Also we demonstrate that there are no cubic vertices describing consistent interaction of continuous-spin massless fields with arbitrary spin massless fields.
