6. 10 things every high-energy physicist should know about cosmology (Enrico Pajer)

Date: April 3rd, 2025 Speaker: Enrico Pajer Title: 10 things every high-energy physicist should know about cosmology Abstract: I will provide a pedagogical review of the connection between quantum field theory and quantum gravity calculations in (quasi) de Sitter spacetime and cosmological data. In particular, I will review the following topics: (i) perturbations are primordial, (ii) adiabatic and isocurvature perturbations, (iii) scale-invariance and boost invariance, (iv) interactions, a.k.a. non-Gaussianity, (v) tensor modes, a.k.a. primordial gravitational waves, (vi) in-in, in-out, Euclidean and wavefunction formalisms, (vii) effective field theories in de Sitter, (viii) cosmological perturbation theory and transfer functions, (ix) current constraints, (x) future forecasts.
