The Joy of Cosmological Correlators - Part 1

This lecture is part of "The Joy of..." series from the KITP Program: What is Particle Theory? (#particles25), featuring Guilherme Pimentel from Pisa discussing cosmological correlators in the first of a two-part presentation. Explore the intersection of formal, computational, and phenomenological theory as it relates to central questions in particle physics. Delve into how diverse perspectives and methods in theoretical physics can accelerate progress toward long-standing goals while potentially generating entirely new questions for the particle theory community. The lecture spans 1 hour and 32 minutes and is part of a field-spanning program aimed at driving theoretical progress through collaborative approaches across different areas of particle theory.
