High Energy LHC Physics

Rutgers has a Unique Strength among US institutions in the close collaboration between Experimental and Theoretical High Energy Physics Groups

The High Energy Experimental Group has extensive experience in Instrumentation and New Physics searches at the Fermilab Tevatron Collider, and is highly regarded within the field

The High Energy Theory Group is already one of the leading Centers for LHC phenomenology

On Our Current Trajectory the combined LHC effort at Rutgers can be at least comparable to that at Berkeley, Stanford, and Princeton, and better than the programs at Harvard, Caltech, Chicago, Yale, and Penn
