Abstract

Amplitudes on the Coulomb branch of N=4 Super-Yang Mills (SYM) provide a rich playground to understand scattering amplitudes involving massive particles. We will discuss a symplectic Grassmannian integral representation of these amplitudes with a particular focus on three point amplitudes. We will discuss on-shell functions and the BCFW bridge on the Coulomb branch and possible future directions to obtain an amplituhedron-like geometry for this theory. Based on arxiv:2311.17763, and ongoing work with Veronica Calvo Cortes, Yassine El Maazouz and Amit Suthar.
