Formalism of gauge invariant curvatures and constructing the cubic vertices for massive spin-3/2 field in AdS_4 space

Understand

We study the interaction of massive spin-3/2 field with electromagnetic and gravitational fields in the four dimensional AdS space and construct the corresponding cubic vertices.

• Construction is based on generalization of Fradkin-Vasiliev formalism, developed for massless higher spin fields, to massive fermionic higher spin fields.
• The main ingredients of this formalism are the gauge invariant curvatures.
• We build such curvatures for the massive theory under consideration and show how the cubic vertices are written in their terms.
