Interplay of Chiral Transitions in the Standard Model
Holger Gies, Richard Schmieden, Luca Zambelli
We investigate nonperturbative aspects of the interplay of chiral transitions in the standard model in the course of the renormalization flow. We focus on the chiral symmetry break…
Background Effective Action with Nonlinear Massive Gauge Fixing
Holger Gies, Dimitrios Gkiatas, Luca Zambelli
We combine a recent construction of a BRST-invariant, nonlinear massive gauge fixing with the background field formalism. The resulting generating functional preserves background-f…
Limit of vanishing regulator in the functional renormalization group
Alessio Baldazzi, Roberto Percacci, Luca Zambelli
The non-perturbative functional renormalization group equation depends on the choice of a regulator function, whose main properties are a "coarse-graining scale" and an overall…
Functional Renormalization and
Alessio Baldazzi, Roberto Percacci, Luca Zambelli
Working with scalar field theories, we discuss choices of regulator that, inserted in the functional renormalization group equation, reproduce the results of dimensional regulariza…
Scheme dependence of asymptotically free solutions
Holger Gies, René Sondenheimer, Alessandro Ugolotti +1
Recent studies have provided evidence for the existence of new asymptotically free trajectories in non-Abelian particle models without asymptotic symmetry in the high-energy limit.…
BRST invariant RG flows
Shimasadat Asnafi, Holger Gies, Luca Zambelli
A mass parameter for the gauge bosons in gauge-fixed four-dimensional Yang-Mills theory can be accommodated in a local and manifestly BRST-invariant action. The construction is bas…
