Abstract:
The proton-proton collisions at the Large Hadron Collider (LHC) produce millions of strongly interacting particles in the form of jets. The large hierarchy of energy scales involved, however, can seriously undermine the convergence of any perturbative calculations. In these scenarios, the Soft-Collinear Effective Theory (SCET) is an appropriate effective field theory that can be used to make systematic improvement. Further complications, however, arise when applying SCET to jet algorithms, which are used by experimentalists to concretely define what a jet is. In this talk, I will first give a brief review of SCET, and then discuss how to consistently apply it to some typical jet definitions.
Coffee and tea will be served 20 minutes prior to the seminar.
