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…

Only Flat Spacetime is Full BPS in Four Dimensional N=3 and N=4 Supergravity
Abhinava Bhattacharjee, Subramanya Hegde, Bindusar Sahoo
We investigate the fully supersymmetric solutions in a class of N=3 and N=4 higher derivative Poincaré supergravity theories. These class of theories are obtained within the framew…
