CERN Theory Department
The Geometry of Particle Physics
Location: 1080 Physics Research Building
Faculty Host: Samir Mathur
Abstract: In this seminar, I will explain that there is a hidden geometry that exists within the Standard Model of Particle Physics. This is due to the modern interpretation of the Standard Model as an Effective Field Theory. I will review this fundamental paradigm and will explain the deep connection between Effective Field Theories and Geometry. This geometric perspective provides key insights into the interpretation of beyond the Standard Model physics, and opens up new and exciting directions for future exploration.
Bio: Prof. Tim Cohen is a theoretical physicist who works on particle physics at the interface between theory and experiment. He is known for his many contributions to beyond the Standard Model theory and phenomenology, with an emphasis on the applications of Effective Field Theory to questions ranging from particle physics to cosmology. He is currently a staff member in the theory department at CERN joint with EPFL, on leave from an Associate Professor position at the University of Oregon. He completed his PhD at the University of Michigan in 2011, followed by two postdoctoral positions, first at SLAC and then as a LHC Theory Initiative Fellow co-hosted by Princeton University and the Institute for Advanced Study.
