Description:

Title: CompEx: A search for Lorentz invariance through Compton scattering

Speaker: Prajwal Mohan-Murthy, Massachusetts Institute of Technology and Paul-Scherrer Institute

Host: Brian Odom 

Abstract: In the recent times, test of Lorentz Invariance has been used as a means to probe theories of physics Beyond the Standard Model, especially those such as extensions to String Theory and Quantum Gravity. Tests of Lorentz invariance could go a long way in setting the stage for possible theories which are beyond the standard model. We describe a simple way of utilizing electron polarimeters, which are a critical beam instrument at precision and intensity frontier nuclear physics labs such as Stanford Linear Accelerator Center (SLAC) and Jefferson Lab (JLab), to limit the dependence of speed of light with the energy of the photons. We also describe a way of limiting directional dependence of speed of light at previously unprecedented levels of precision by studying the sidereal variations. The method and preliminary results from this study as well as possible limits on CPT violating Standard Model Extension parameters will be presented.
