Higher spin amplitudes in supersymmetric theories

We use massive spinor helicity formalism to write down the
tree-level four-point function of massless particles for $\mathcal{N}=1$,
$2$ and $4$ theories. In particular, we derive the expressions for
four-photon/gluon amplitudes with massive higher spin exchange in theories
with $\mathcal{N}=4$ Supersymmetry in 3+1 dimensions.
