报告人介绍

Dr. Luca Di Luzio is a staff researcher at the University of Padua (Italy). He works on phenomenological aspects of fundamental interactions and particle cosmology. In particular, his recent interests have been focused on axion physics, with applications at the interface between particle physics, astrophysics and cosmology.

报告摘要

This is an introductory course on axion physics, addressed to students with a basic background on quantum field theory and the standard model of particle physics. We will primarily focus on particle physics aspects and motivate the introduction of the axion field from the standpoint of the strong CP problem. Next, we will explicitly compute basic axion properties and discuss some axion models. We will finally conclude with a brief overview of axion phenomenology.
