On Equations for a Spin-2 Particle in External Gravitational Field
msra(2003)
Abstract
30-component, of the first order, equation for a spin 2 particle, equivalent
to the second order Pauli-Fierz one, is generalized to presence of an external
electromagnetic field as well as a curved background space-time geometry. The
essential property of the generally covariant wave equation obtained is that
here from the very beginning, in accordance with requirement of the Pauli-Fierz
approach, a set of additional relations on 30-component wave function for
eliminating complementary spin 0 and spin 1 fields is present at the starting
equation.
