A Positive-Definite Scalar Product for Free Proca Particle
arXiv:hep-th/0610290 · doi:10.1007/s10582-006-0394-x
Abstract
We implement recent results of pseudo-Hermitian quantum mechanics to description of relativistic massive particle with spin-one. We derive a one-parameter family of Lorentz invariant positive-definite scalar products on the space of solutions of Proca equation.
