- Theoretical cosmology: Sebastián Cespedes (Imperial) on 8th May 2024 1:00:pm Title: On the IR divergences in de Sitter: loops, resummation and the semi-classical wavefunction Abstract: Detecting local Non-Gaussianity provides valuable insights into the early universe’s particle composition. Interactions between the inflaton and light particles yield distinctive signatures, potentially observable in upcoming surveys. However, addressing IR divergences in light fields on de Sitter spacetimes requires careful treatment. Stochastic...
