Scattering Amplitudes in Gauge Theory as Chiral Algebra Correlators - Kevin Costello

Explore a high-energy theory seminar on scattering amplitudes in gauge theory presented by Kevin Costello from Perimeter Institute at the Institute for Advanced Study. Delve into the derivation of expressions for form factors and scattering amplitudes as correlators of a chiral algebra, closely related to algebras in the celestial holography program. Examine topics such as form factor integrands, theory on twistor space, LEA theory, mode algebra, vacuum module, momentum modes, conformal blocks, and amplitudes. Investigate examples, the Park-Taylor formula, one-loop amplitudes, multiple loop diagrams, and the axion kinetic term. Gain insights into this cutting-edge research in theoretical physics through the presentation and subsequent question-and-answer session.
