Title:  The Precision Frontier of Particle Physics

Host: Csaba Csaki

Abstract:  High precision technology offers a powerful new approach for particle physics.  Discovering the answers to open questions such as the hierarchy problem and the nature of dark matter may in fact require a new, high precision approach instead of conventional techniques.  Examples of such new physics include the axion, a solution to the strong CP problem and strongly-motivated dark matter candidate, as well as a recently proposed solution to the hierarchy problem using dynamical relaxation in the early universe.  Technologies such as atom interferometry, nuclear magnetic resonance, and high precision magnetometry allow novel, highly sensitive experiments for direct detection of dark matter and new fundamental interactions. These technologies are similar in many respects to gravitational wave detectors and in fact may also allow detection of gravitational waves over new frequency bands.  Such precision experiments will open new avenues for probing the origin and composition of the universe.
