Leading soft theorem for multiple gravitini

Understand

We compute leading soft theorem for multiple gravitinos (and graviton) in an arbitrary theory of supergravity with an arbitrary number of finite energy particles with arbitrary mass and arbitrary spin by extending Sen's approach \cite{Sen:2017xjn} to fermionic symmetry.

• Our result is true for any compactification of type II and Heterotic superstring theory.
• Our result is valid at all orders in perturbation for four and higher spacetime dimensions.
