Fixed Points of 4d Gauge Theories Ultraviolet (UV) fixed points are key for a fundamental definition of quantum field theory, and the existence of free UV fixed points, asymptotic freedom, has been known [...] fixed points of gauge theories with matter. After reviewing earlier findings, I report new results at 4-loop order in perturbation theory. Emphasis is put on the size of the conformal window, and whether …
