Symplectic Grassmannian description of the Coulomb branch three and four point amplitudes

Veronica Calvo Cortes, Yassine El Maazouz, Subramanya Hegde +1

We present a formulation of the three- and four-point amplitudes on the Coulomb branch of N=4 SYM as integrals over the symplectic Grassmannian. We demonstrate that their kinematic…
