Particle Theory Seminar | Nathaniel Craig (UCSB) – Effective Field Theory and the Geometry of Electroweak Symmetry Breaking
–
Abstract: There are two canonical approaches to treating the Standard Model as an effective field theory: the Standard Model EFT (SMEFT), respecting the full electroweak gauge symmetry, and the Higgs EFT (HEFT), respecting only electromagnetism. Of these, SMEFT has become the predominant framework for interpreting LHC Higgs data and exploring the systematics of effective field theory. This raises a number of questions: Is … Read More
