TL;DR

This paper develops a method to determine non-factorizable superamplitudes for massive N=1 superstates, using symmetry principles and massless limits, applicable regardless of superstate conjugation or form-factor dressing.

Contribution

It introduces a novel approach to derive massive superamplitudes from massless ones using symmetry constraints and zero-mass limits, independent of superstate conjugation.

Findings

Derived form of non-factorizable massive superamplitudes

Established reduction to massless superamplitudes in zero-mass limit

Applicable to both Dirac and Majorana superstates

Abstract

In this paper we study non-factorizable N = 1 superamplitudes for massive chiral superstates. We demonstrate how little group scaling and the supersymmetric Ward identities determine the form of non-factorizable massless superamplitudes, then extrapolate to massive superamplitudes by requiring they reduce to the massless form when we send all masses to zero. This technique does not depend on whether or not the superstates are self-conjugate (so that the fermionic components are either Dirac or Majorana) or whether the superamplitude is dressed with a form-factor.
