Axion dark matter with low-scale inflation

Ottobre 28, 2021@11:00 am–12:00 pm
Aula 603 e online

Seminario di Fenomenologia delle Particelle Elementari INFN/DIFI – Dr Lorenzo Ubaldi (SISSA)

After a brief introduction to the strong CP problem, I will introduce the axion as a solution and explain how it also provides a cold dark matter candidate. In the second part of my talk I will focus on cosmological scenarios with a low scale of inflation, and discuss a mechanism that can generate enough axion relics to match the observed dark matter abundance even in such scenarios.
