This 15-minute conference talk by Arhum Ansari explores inflationary non-Gaussianities in alpha vacua and their consistency with conformal symmetry as part of the "Positive Geometry in Scattering Amplitudes and Cosmological Correlators" program at the International Centre for Theoretical Sciences. Delve into the intersection of mathematical aspects of scattering amplitudes and cosmology, connecting these seemingly different fields of theoretical physics. The program, organized by Nima Arkani-Hamed, Johannes Henn, Suvrat Raju, and Jaroslav Trnka, aims to advance understanding of perturbative on-shell scattering amplitudes and their connection to positive geometry, while exploring similar structures observed in cosmological correlators that capture the physics of our Universe.
