Title:     Effective Field Theory and Collider Physics

Abstract: Effective field theories are powerful but underappreciated tools for collider physics. In a high-energy collision there are often many scales relevant to observables of interest, such as the energies of different jets in a multijet distribution. Effective field theories allow us to separate the physics at each scale from the physics between scales leading to theoretical calculations with unprecedented accuracy. There are important applications to colliders of the past, present, and future, such as measuring alpha_s at LEP, finding the higgs at the Tevatron, and understanding supersymmetry at the LHC. In addition, effective field theories may be critical to solving a universal problem in collider physics: designing a systematically improvable monte carlo event generator. I will present an overview of the effective field theory approach and describe in detail a few of the applications.

Stimulants available 15 minutes before the talk.
