Event details

I will present some recent calculations of the RG flow of gravitational central charges in gauge theories. In our approach the running of the gauge coupling is absorbed into the metric by applying combination of field rescaling and Weyl-transformation. The computation then becomes equivalent to the one on curved background carrying the information of the renormalisation group flow. We use the techniques of conformal anomaly matching and dilaton effective action, by Komargodski and Schwimmer, to find the flow of the Euler anomaly coefficient between two fixed points of the flow.

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
