General Wigner Rotations in Dimensions
arXiv:1612.09392
Abstract
We construct general Wigner rotations for both massive and massless particles in -dimensional spacetime. We work out the explicit expressions of these Wigner rotations for arbitrary Lorentz transformations. We study the relation between the electromagnetic gauge invariance and the non-uniqueness of Wigner rotation.
