Symbol Alphabets from Plabic Graphs III: n=9
Jorge Mago, Anders Schreiber, Marcus Spradlin +2
Symbol alphabets of n-particle amplitudes in N=4 super-Yang-Mills theory are known to contain certain cluster variables of Gr(4,n) as well as certain algebraic functions of cluster…
Symbol Alphabets from Plabic Graphs II: Rational Letters
Jorge Mago, Anders Schreiber, Marcus Spradlin +2
Symbol alphabets of n-particle amplitudes in N=4 super-Yang-Mills theory are known to contain certain cluster variables of Gr(4,n) as well as certain algebraic functions of cluster…
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…
Cutting Deep Into The Amplituhedron
Nima Arkani-Hamed, Cameron Langer, Akshay Yelleshpur Srikant +1
In this letter we compute a canonical set of cuts of the integrand for MHV amplitudes in planar SYM, where all internal propagators are put on-shell. These "deepest cu…
