Non-BPS supersymmetric 3pt amplitude for one massless, two equally massive particles
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 wi...

| Sumario: | 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. |
