Abstract

We describe a five-dimensional analogue of Wigner's operator equation Wa=λPa{\mathbb W}_a = \lambda P_a, where Wa{\mathbb W}_a is the Pauli-Lubanski vector, PaP_a the energy-momentum operator, and λ\lambda the helicity of a massless particle. Higher dimensional generalisations are also given.
