On Positive Geometry and Scattering Forms for Matter Particles
Aidan Herderschee, Song He, Fei Teng +1
We initiate the study of positive geometry and scattering forms for tree-level amplitudes with matter particles in the (anti-)fundamental representation of the color/flavor group.…

Constructing Coulomb Branch Superamplitudes
Aidan Herderschee, Seth Koren, Timothy Trott
We study scattering amplitudes of massive BPS states on the Coulomb branch of super-Yang-Mills, utilising a little group covariant on-shell superspace for mass…

Massive On-Shell Supersymmetric Scattering Amplitudes
Aidan Herderschee, Seth Koren, Timothy Trott
We introduce a manifestly little group covariant on-shell superspace for massive particles in four dimensions using the massive spinor helicity formalism. This enables us to constr…
