Interacting Rarita--Schwinger Field and its Spin-Parity Content
A. E. Kaloshin, V. P. Lomov
Abstract
We obtain in analytical form the dressed propagator of the massive Rarita-Schwinger field and discuss its properties. The calculation of the self-energy contributions demonstrates that besides s=3/2 component the Rarita-Schwinger field contains also two s=1/2 components of opposite parity.
