Geometry of the 2-loop MHV amplituhedron


  • Mr. Ryota KOJIMA


Nima arkani-Hamed and Jaroslav trnka found a new mathematical object, "the Amplituhedron" that its 'volume' is the amplitude in planar N=4 SYM. We found a new explicit formula for the n-pt 2-loop MHV amplitude from the amplituhedron and obtain some properties of the amplitude from this result. In this talk, I will briefly explain the definition of the amplituhedron and our results about a geometry of the 2-loop amplituhedron.
