[Seminar] "New triangulation of the Amplituhedron from sign flip" by Ryota Kojima

Quantum Gravity Unit (Neiman Unit) would like to invite you to a seminar by Ryota Kojima from KEK, Japan

Title: "New triangulation of the Amplituhedron from sign flip"

Abstract:
Perturbative scattering amplitudes in gauge theories have remarkable simplicity and hidden infinite dimensional symmetries that are completely obscured in the conventional formulation of field theory using Feynman diagrams.
Nima arkani-Hamed and Jaroslav trnka found a new mathematical object, the Amplituhedron that its 'volume' is the amplitude in planar N=4 SYM.
There are two definition of the Amplituhedron. It has a structure like a polyhedron and it can think a triangulation of it. This triangulation is related to the recursion relation of the amplitude like BCFW.
We found a new way of triangulation for the n-pt 2-loop MHV Amplituhedron in the progress work. In this talk, I will briefly explain the definition of the amplituhedron and its property, then I will talk a new triangulation.
