Research: Theoretical Particle Physics

Adam Leibovich is an undergraduate advisor.

My research interests centers on the strong and weak interactions of the Standard Model. In particular, I use effective field theory techniques to study heavy quarks as a probe of these interactions, and to try to uncover physics beyond the Standard Model. I am also interested in the physics of extra dimensions, supersymmetry, and in matter at extreme densities. I plan on working more on physics relevant to the Large Hadron Collider, the new particle accelerator at CERN outside Geneva that will begin taking data in 2009.
