Abstract

We present a Lagrangian formulation for 4d integer-spin relativistic fields in the 5d space spanned by two conjugate Weyl spinors and a Lorentz-invariant proper-time coordinate. We construct a manifestly Poincare-invariant free classical action, find a general solution to equations of motion and a corresponding positive-definite inner product. Our formulation displays a separation of variables: equations of motion represent ODE in a proper time only, while spinor coordinates parameterize the Cauchy hypersurface. We also find momentum eigenstates solutions for massless arbitrary integer-spin fields and a massive scalar field.
