Massive spin-2 in the Fradkin-Vasiliev formalism. I. Partially massless case

TL;DR

This paper uses the Fradkin-Vasiliev formalism to construct cubic interaction vertices for partially massless spin-2 particles, focusing on self-interactions and gravitational interactions as a foundational example.

Contribution

It introduces a novel application of the Fradkin-Vasiliev formalism to partially massless spin-2 particles, detailing the construction of interaction vertices.

Findings

Successfully constructed cubic interaction vertices for partially massless spin-2.

Demonstrated the applicability of the formalism to self and gravitational interactions.

Provided a groundwork for further studies on higher-spin interactions.

Abstract

We apply Fradkin-Vasiliev formalism to construction of non-trivial cubic interaction vertices for massive spin-2 particles. In this first paper as a relatively simple but instructive example we consider self-interaction and gravitational interaction of partially massless spin-2.
