005 h: 14:30 Conformality Loss, Walking, and 4d Complex CFTs at Weak Coupling
Marco Serone Four-dimensional gauge theories can flow in the infrared to non-trivial conformal field theories. It has been conjectured that conformality can be lost because of merging of two nearby fixed points that move into the complex plane, and that a walking dynamics governed by scaling dimensions of operators defined at such complex fixed points can occur. Controlled, parametrically weakly-coupled, and ultraviolet-complete 4d gauge theories that explicitly realize this scenario are presented.
