Leading soft theorem for multiple gravitini

Abstract

Abstract We compute leading soft theorem for multiple gravitini (and gravitons) in an arbitrary theory of supergravity with an arbitrary number of finite energy particles by extending Sen’s approach [1, 2] to fermionic symmetry. Our results are independent of the mass and the spin of the external particles. Our results are valid for any compactification of type II and Heterotic superstring theory. Our results are valid at all orders in perturbation theory for four and higher spacetime dimensions.
