Abstract
- In this work we take a formal approach to the problem of decoupling Proca equations in curved space-times. We use Newman-Penrose two-spinor formalism to represent the Proca vector by one complex and two real scalars. We show that a decoupled second order differential equation for one of the real scalars can be derived if and only if the background space-time admits a covariantly constant null vector. Thus, the background space-time must be a pp-wave vacuum. We evaluate the separability of Proca, Maxwell and Dirac equations on the resulting pp-wave background. [ABSTRACT FROM AUTHOR]
