Amplituhedron Theory: A Geometric Approach to Particle Interactions in Quantum Field Theories

  Abstract: In this paper, we explore the amplituhedron theory introduced by Nima Arkani-Hamed and Jaroslav Trnka in 2013, which provides a geometric framework for calculating particle interactions in some quantum field theories. We discuss the positive Grassmannian and its connection to scattering amplitudes, the role of twistor string theory, and the implications of the […]
