The polarized scattering equations for 6d superamplitudes

Understand

We introduce a spinorial version of the scattering equations, the \emph{polarized scattering equations}, that incorporates spinor polarization data.

• They lead to new formulae for tree-level scattering amplitudes in six dimensions that directly extend to maximal supersymmetry.
• They give a quite distinct framework from that of Cachazo et al.; in particular, the formulae do not change character from even to odd numbers of particles.
• We find new ingredients for integrands for maximally supersymmetric Yang-Mills, gravity, M5 and D5 branes.
