Hidden Sector Custodial Naturalness

Thede de Boer, M. Lindner, Andreas Trautner

Custodial naturalness is a recently introduced idea that combines conformal and scalar sector custodial symmetry to address the electroweak (EW) scale hierarchy problem of the standard model (SM). We introduce a new model that realizes custodial naturalness without extension of the SM …

Outer automorphisms are sufficient conditions for RG fixed points

Thede de Boer, Andreas Trautner

We point out that the existence of an outer automorphism (Out) is a sufficient condition for the existence of a fixed hyperplane (fixed point, separatrix) in the renormalization group (RG) flow of a Quantum Field Theory (QFT). The corresponding RG fixed hyperplane …

Goofy transformations and the hierarchy problem

Andreas Trautner

Goofy transformations of the Standard Model (SM) Higgs field generally prohibit its bare mass term. This opens up an entirely new class of solutions to the electroweak (EW) hierarchy problem. We argue that these can be intrinsically linked to the flavor structure …

Symmetries from outer automorphisms and unorthodox group extensions

C. Döring, Andreas Trautner

Abstract Symmetries play an essential role in the construction and phenomenology of quantum field theories (QFTs). We discuss how to construct symmetries of QFTs by extending minimal ‘seed’ symmetry groups to larger groups that contain the seed(s) as subgroup(s). On the one …

Goofy is the new Normal

Andreas Trautner

A bstract We discuss the recently discovered global goofy transformations and conclude that their understanding is mandatory to describe the renormalization group (RG) fixed point structure of quantum field theories (QFTs) in general. Originally, goofy transformations were identified in the two-Higgs-doublet model …

Custodial Naturalness

Thede de Boer, M. Lindner, Andreas Trautner

A bstract Custodial Naturalness is a new symmetry-based idea to explain the large separation between the electroweak (EW) scale and ultraviolet completions of the Standard Model (SM). Classical scale invariance is combined with an enhanced scalar-sector custodial symmetry and both are spontaneously …

Custodial Naturalness is a new symmetry-based idea to explain the large separation between the electroweak (EW) scale and ultraviolet completions of the Standard Model (SM).

Electroweak hierarchy from conformal and custodial symmetry

Thede de Boer, M. Lindner, Andreas Trautner

We present “Custodial Naturalness” as a new mechanism to explain the separation between the electroweak (EW) scale and the scale of potential ultraviolet completions of the Standard Model (SM). We assume classical scale invariance as well as an extension of the SM …

The eclectic flavor symmetries of $$ {\mathbbm{T}}^2/{\mathbb{Z}}_K $$ orbifolds

Alexander Baur, Hans Peter Nilles, Saúl Ramos–Sánchez, Andreas Trautner et autres

A bstract Only four $$ {\mathbbm{T}}^2/{\mathbb{Z}}_K $$ T 2 / ℤ K orbifold building blocks are admissible in heterotic string compactifications. We investigate the flavor properties of all of these building blocks. In each case, we identify the traditional and modular flavor …
