Linear equations of motion for massless particles of any spin in any even dimensional spaces
Abstract
It is proven that the Poincare symmetry determines equations of motion, which are for massless particles of any spin in ddimensional spaces linear in the momentum. The proof is made only for even d and for fields with no gauge symmetry. We comment on a few examples. We pay attention only to spin degrees of freedom.
