Spherical Contours, IR Divergences and the geometry of Feynman parameter integrands at one loop
Akshay Yelleshpur Srikant
Spherical contours introduced in \cite{SphericalContours} translate the concept of "discontinuity across a branch cut" to Feynman parameter space. In this paper, we further explore…

Emergent unitarity from the amplituhedron
Akshay Yelleshpur Srikant
We present a proof of perturbative unitarity for SYM, following from the geometry of the amplituhedron. This proof is valid for amplitudes of arbitrary multiplicity…

All-loop cuts from the Amplituhedron
Cameron Langer, Akshay Yelleshpur Srikant
The definition of the amplituhedron in terms of sign flips involves both one-loop constraints and the "mutual positivity" constraint. To gain an understanding of the all-loop integ…
