Scholar-generated biography
Samuel Abreu is a researcher specializing in high-energy physics, with a focus on scattering amplitudes and their mathematical structures. His work explores the analytic forms of multi-loop amplitudes in quantum chromodynamics (QCD) and super-Yang-Mills theory, emphasizing numerical unitarity and Feynman integrals. He has contributed to the study of planar and nonplanar multi-loop processes, including five-parton amplitudes and their applications in heavy-ion collisions. His research also involves the algebraic and diagrammatic properties of Feynman integrals, including their coaction and Hopf algebra structures. Abreu's publications often address the computation of two-loop amplitudes and their implications for collider physics.
