Higgs in Abelian and Non-Abelian Flavor Symmetry Models
Julian Heeck, Martin Holthausen, Werner Rodejohann +1
We study lepton flavor violating Higgs decays in two models, with the recently found hint for Higgs at CMS as a benchmark value for the branching ratio. The first model us…
Electroweak and Conformal Symmetry Breaking by a Strongly Coupled Hidden Sector
Martin Holthausen, Jisuke Kubo, Kher Sham Lim +1
The LHC and other experiments show so far no sign of new physics and long-held beliefs about naturalness should be critically reexamined. We discuss therefore in this paper a model…
Solving the Strong CP Problem with Discrete Symmetries and the Right Unitarity Triangle
Stefan Antusch, Martin Holthausen, Michael A. Schmidt +1
We present a solution to the strong CP problem based on spontaneous CP violation and discrete family symmetries. The model predicts in a natural way the almost right-angled quark u…
Quark and Leptonic Mixing Patterns from the Breakdown of a Common Discrete Flavor Symmetry
Martin Holthausen, Kher Sham Lim
Assuming the Majorana nature of neutrinos, we recently performed a scan of leptonic mixing patterns derived from finite discrete groups of order less than 1536. Here we show that t…
Lepton Mixing Patterns from a Scan of Finite Discrete Groups
Martin Holthausen, Kher Sham Lim, Manfred Lindner
The recent discovery of a non-zero value of the mixing angle theta_13 has ruled out tri-bimaximal mixing as the correct lepton mixing pattern generated by some discrete flavor symm…
CP and Discrete Flavour Symmetries
Martin Holthausen, Manfred Lindner, Michael A. Schmidt
We give a consistent definition of generalised CP transformations in the context of discrete flavour symmetries. Non-trivial consistency conditions imply that every generalised CP…
Lepton flavor at the electroweak scale: A complete A4 model
Martin Holthausen, Manfred Lindner, Michael A. Schmidt
Apparent regularities in fermion masses and mixings are often associated with physics at a high flavor scale, especially in the context of discrete flavor symmetries. One of the ma…
Proceedings of the 2nd Workshop on Flavor Symmetries and Consequences in Accelerators and Cosmology (FLASY12)
I. de Medeiros Varzielas, C. Hambrock, G. Hiller +66
These are the proceedings of the 2nd Workshop on Flavor Symmetries and Consequences in Accelerators and Cosmology, held 30 June 2012 - 4 July 2012, Dortmund, Germany.
Planck Scale Boundary Conditions and the Higgs Mass
Martin Holthausen, Kher Sham Lim, Manfred Lindner
If the LHC does only find a Higgs boson in the low mass region and no other new physics, then one should reconsider scenarios where the Standard Model with three right-handed neutr…
Natural Vacuum Alignment from Group Theory: The Minimal Case
Martin Holthausen, Michael A. Schmidt
Discrete flavour symmetries have been proven successful in explaining the leptonic flavour structure. To account for the observed mixing pattern, the flavour symmetry has to be bro…
GIMPs from Extra Dimensions
Martin Holthausen, Ryo Takahashi
We study a scalar field theory in a flat five-dimensional setup, where a scalar field lives in a bulk with a Dirichlet boundary condition, and give an implementation of this setup…
Radiative Symmetry Breaking of the Minimal Left-Right Symmetric Model
Martin Holthausen, Manfred Lindner, Michael A. Schmidt
Under the assumption of classical conformal invariance, we study the Coleman-Weinberg symmetry breaking mechanism in the minimal left-right symmetric model. This model is attractiv…
