Abstract:
In this talk, we delve into the fascinating world of scattering amplitudes, exploring their hidden structures and unveiling new physics. We investigate the concept of double copy, establishing intriguing connections between gauge theory and gravitational scattering amplitudes. Leveraging modern computational methods and powerful duality frameworks, we explore the broad applications of the double copy across various regimes, from tree-level to the quantum regime, simplifying the computations of super Yang-Mills theory and supergravity amplitudes. Additionally, we delve into string-like methods and their role in evaluating loop-level amplitudes, revealing the intricate interplay between string theory and field theories. Lastly, we embark on a journey into the realm of generalized biadjoint theories, examining their Feynman diagrams and configuration spaces, thereby paving the way for new theories and offering novel insights.
