The Standard Model of strong, electromagnetic and weak interactions is the crowning achievement of twentieth century physics. However, despite its many spectacular successes, the Standard Model is inconsistent at high energies and should be superseded by a new, more fundamental theory at the teraelectron-volt (TeV) energy scale. Many theoretical ideas about the nature of the physics at the TeV scale have been proposed, examples include: supersymmetry, extra dimensions of space and new strong interactions. Members of the Cornell theory group are active in investigating these ideas. While so far this work has been purely theoretical, the experimental investigation of the TeV scale began in late 2009, when the Large Hadron Collider (LHC) at the CERN laboratory in Switzerland began operations. Theoretical interpretation of the LHC data is expected to be a major focus of research in the next few years. In this work, Cornell theorists will benefit from traditionally close connections with the LEPP experimental group, which is participating in the CMS experiment at the LHC.
