Dark matter is believed to make up most of the matter of our Universe, but its particle origin remains a mystery. So far experimental searches for dark matter particles have largely focused on the mass window at around the Hoggs boson mass. At the same time, lighter dark matter candidates in a dark sector are theoretically well-motivated and arise generically in many theories beyond the Standard Model. In this colloquium, I will first present an overview of the most recent progress exploring light dark matter candidates at high energy and high intensity colliders, highlighting the role of the Higgs boson in this endeavor. Then I will motivate new searches and new collider experiments that will have a unique opportunity to broadly explore viable light dark matter models.
Stefania Gori is a theoretical particle physicist working at the University of California, at Santa Cruz.
She obtained her master degree in physics at the Scuola Normale of Pisa (Italy), and then moved to the Technical University of Munich (Germany), where she got her PhD in 2010. She was a postdoctoral fellow at the University of Chicago, and at the Perimeter Institute for theoretical physics in Waterloo, Canada.
Prof. Gori was a faculty at the University of Cincinnati in 2016-2018 and then joined the faculty of UCSC as an assistant professor in 2018. She is a recipient of the prestigious National Science Foundation Career award. Prof. Gori's work in particle physics has ranged over several topics, including Higgs physics, the physics of Dark Matter, flavor physics, and neutrino physics.
