Inverse Soft Construction of Scattering Amplitudes

This lecture explores the inverse soft construction of scattering amplitudes, presented by Saurabh Pant at the International Centre for Theoretical Sciences. Learn about the mathematical aspects of scattering amplitudes and their connections to positive geometry during this 16-minute talk from the "Positive Geometry in Scattering Amplitudes and Cosmological Correlators" program. The workshop brings together experts from scattering amplitudes and cosmology fields, exploring connections between perturbative on-shell scattering amplitudes and cosmological correlators through unitarity methods, recursion relations, worldsheet models, bootstrap methods, and their relationships to positive geometry, positive Grassmannian, Associahedron, and the Amplituhedron. Discover how these approaches are pushing toward a reformulation of the perturbative S-matrix using entirely new principles.
