Non-BPS Supersymmetric 3pt Amplitude for One Massless, Two Equally Massive Particles

Abstract

In this paper, the non-BPS amplitudes ($Z<2m$) are considered. Utilizing on-shell methods, the three point amplitudes of two equal-mass particles and one massless particle were constructed, where the two massive particles are non-BPS states. We verify the result by matching the $Z=0$ and BPS limit with $N=2$ supersymmetry. As an application we derive the non-BPS coupling for $N=4$ super-Maxwell and supergravity.
