We study the high-energy behaviour of interacting non-Abelian
gauge fields, fermions, and scalars. In a regime where asymptotic
freedom is absent, we find that the three types of fields cooperate
to develop an interacting UV fixed point, strictly controlled by
perturbation theory. The key features of asymptotic safety for
UV model building and particle phenomenology are discussed.

The Peccei-Quinn mechanism is perhaps the most compelling solution we have for the strong-CP problem. The mechanism predicts the existence of a pseudo-Goldstone boson, the axion, which could account for the dark matter content of the Universe. The smallness of active neutrino masses can also be explained in axion models via a type-I see-saw mechanism, providing a dynamical origin for the...

We extend the two-Higgs doublet models of Type I and Type II by adding a real gauge-singlet scalar S which is the Dark Matter (DM) candidate (2HDMS models). We impose theoretical constraints derived from perturbativity, stability, unitarity and correct electroweak symmetry breaking and require that one of CP-even Higgs bosons fit the LHC data for the ∼125.5 GeV state at the 68%~C.L. after...

In this talk I will discuss weak-scale extensions of the Standard Model which automatically preserve the accidental and approximate symmetry
structure of the Standard Model and which are hence invisible to indirect low-energy probes. By requiring the consistency of the effective field
theory up to scales of $\Lambda_{eff}=10^{15}$ GeV and after applying cosmological constraints, there is...

Several aspects of the MFV implementation in the presence of global U(1)
flavor symmetries will be discussed. Some generic implications for baryon
number violation, lepton number violation and Majorana mass terms, and axion
dynamics will be drawn.

I comment shortly on various mechanisms for electric dipole moments. I also comment on recent calculations of two loop diagrams for electric dipole moments generated by flavor changing scalars.

Rare b decays are investigated in the Randall Sundrum model with
custodial symmetry. Correlations among the observables are studied,
and predictions for unobserved modes are presented.

I will report on recent analyses of rare K and B decays done at TUM-IAS which with improved data should provide in this decade some insight into the dynamics at the LHC scales and beyond them.
