ITMP Seminar "Models for a vast energy range: particles meet gravity and cosmology"

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Apr 21, at 18:00 (Moscow time). The seminar will be arranged via Zoom.

Speaker: Alberto Salvio, University of Rome Tor Vergata

Title: Models for a vast energy range: particles meet gravity and cosmology

Abstract: I will discuss models valid over a vast energy range by following 2 strategies. In one approach (bottom-up) I will illustrate the main phenomenological aspects of a scenario where one adds to the Standard Model 3 right-handed neutrinos and an axion sector. This can account for neutrino oscillations, dark matter, baryogengesis, inflation and can also stabilize the electroweak vacuum. In another, more ambitious approach, I will talk about a scenario where all couplings flow to zero at infinite energy (total asymptotic freedom).  The corresponding phenomenology of this top-down approach will also be treated.

If you want to join the seminar please register here before 14:00, April 21.
