Colloquium on Oct. 15, 2021

Introduction to Modified Gravity: From Dark Side of Universe to Particle Physics


Speaker: Taishi Katsuragawa (CCNU)

Venue: Room 2111, SWIFAR Building

Time: 10:00 AM, Friday, Oct. 15, 2021

Abstract:

With an overview of the modified gravity theory from cosmological viewpoints, this talk will provide a new paradigm to unify dark energy and dark matter in a framework of F(R) gravity theory. The F(R) gravity includes the extra scalar field, scalaron, in addition to the graviton. We discuss the possibility that the scalaron particle is a dark matter candidate and the new scalaron search experiment based on the stimulated photon-photon collider concept.
