Towards positive geometry of multi scalar field amplitudes. Accordiohedron and effective field theory
Abstract The geometric structure of S-matrix encapsulated by the “Amplituhedron program” has begun to reveal itself even in non-supersymmetric quantum field theories. Starting with the seminal work of Arkani-Hamed, Bai, He and Yan [1] it is now understood that for a wide class of scalar quantum fiel...
