Massive higher spin fields in the frame-like multispinor formalism

Understand

In this paper, a gauge invariant description of massive higher spin bosonic and fermionic particles in frame-like Lagrangian and unfolded formalism in (A)dS${}_4$ is built.

• A complete set of gauge invariant object is also constructed and the Lagrangian is rewritten in terms of these objects.
• The unitarity of the theories is studied alongside with the partially massless limits.
• The calculations are carried out in the multispinor formalism, which simplifies them and is particularly convenient for the supersymmetry studies.
