The renormalization group plays an essential role in many areas of physics, both
conceptually and as a practical tool to determine the long-distance low-energy properties of …

Yang–Mills theories are an important building block of the standard model and in particular
of quantum chromodynamics. Its correlation functions describe the behavior of its …

These lecture notes give an introduction to the functional renormalisation group and
asymptotically safe quantum gravity. We cover the basics of generating functionals in …

Abstract Brout–Englert–Higgs physics is one of the most central and successful parts of the
standard model. It is also part of a multitude of beyond-the-standard-model scenarios. The …

Quantum scale symmetry is the realization of scale invariance in a quantum field theory. No
parameters with dimension of length or mass are present in the quantum effective action …

We present a comprehensive non-perturbative study of the phase structure of the
asymptotically safe Standard Model. The physics scales included range from the …

We explore a simple parameterization of new physics that results in an ultraviolet complete
gauge-quark sector of the Standard Model. Specifically, we add an antiscreening …

A bstract We study the renormalization group flow of gravity coupled to scalar matter using
functional renormalization group techniques. The novel feature is the inclusion of higher …

The link between a modified Higgs self-coupling and the strong first-order phase transition
necessary for baryogenesis is well explored for polynomial extensions of the Higgs …

We discuss the phase structure of the two-flavor quark-meson model including quantum,
thermal, density and critical fluctuations with the functional renormalization group. This study …
