Theoretical Cosmology meetings

To actively encourage the field of theoretical cosmology and to set an informal stage for the exchange of ideas, the Dutch theoretical cosmology community organizes Friday afternoon meetings approximately 6 times a year — usually on the first Friday of the month. The meetings typically start in the afternoon with a main speaker, followed by a short break to continue with another seminar or journal club discussion on some topic of current interest. We end the afternoon with drinks. The supporting institutes in Leiden, Amsterdam, Groningen, Utrecht where recently joined by the strings and cosmology group in Leuven and take turns in hosting the event.

Utrecht on Friday, June 2, 2017

Location: Atlas Lecture Hall, Koningsberger Building, Utrecht Science Park


13:30 – 14:00 Tea & Coffee

14:00 – 15:00 Talk by Brando Bellazzini (IPhT CEA Saclay)

Title: Softness, amplitudes’ positivity, and EFT for spinning particles.

Abstract: Not every EFT admits a UV completion which is consistent with S-matrix theory. I will review some of the constraints  that come from analyticity, crossing symmetry and unitarity of the underlying UV theory, with emphasis on the case of EFT that contains spinning particles in the IR, including massless spin-1/2 fermions and the spin-2 graviton.

15:00 – 15:30 Coffee Break
