# Perturbative Approaches for QED3

Friday, April 13, 2018
11:00 AM - 12:00 PM
Location: Lauritsen 469
Lorenzo Di Pietro, Perimeter Institute

In the first part of my talk I will present the epsilon-expansion results for the scaling dimensions of bilinear (3-loops) and four-fermion operators (2-loops) in the IR fixed point of QED in 3d. In the second part I will describe a different calculable limit of QED in 3d, obtained by considering the coupling of a 4d free abelian gauge field to matter on a 3d boundary.
