Particle Physics Seminar
"New Optical Techniques for Studying Vacuum Birefringence"
Presented by Carol Y. Scarlett, Florida A&M University
Thursday, August 20, 2015, 3:00 pm — Small Seminar Room, Bldg. 510
The search for Axions, a particle theorized to explain the lack of CP violation in strong physics and suspected to contribute if not explain galactic dark matter, has lead to ever-sensitive techniques to study induced vacuum birefringence. What remains an issue: many of the measurable parameters that could give evidence for this illusive particle scale with the square of the birefringent angle (proportional to the photon-axion coupling constant). This talk will look at new techniques that can generate measurables that scale linearly (first order) with an induced birefringence. This has the potential to extend significantly the range through which cavity experiments can probe the vacuum of space in performing searches for axions and other exotic particles.
