Particle Phenomenology
Much progress has been made in recent years towards a field-theoretic understanding of quantum gravity within the asymptotic safety conjecture. In this talk, I report progress towards the inclusion of Standard Model matter. We perform an extensive fixed point search in theories involving Ricci scalar and tensor, and Riemann tensor invariants alongside SM matter, up to high polynomial orders in...

Despite its many successes the Standard Model can at best be viewed
as a low energy approximation to a more fundamental theory of nature.
Supersymmetry provides a theoretically attractive extension of the
Standard Model while the idea of asymptotic safety leads to field theories
which can be regarded as being fundamental.
In this talk I investigate whether and how the minimal...

I will discuss asymptotically safe extensions of the Standard Model with new matter fields at the TeV scale. The BSM sector contains singlet scalars and vector-like fermions in representations which permit Yukawa interactions with the Standard Model leptons and a Higgs portal coupling. UV safety is explored up to the Planck regime in dependence of the BSM couplings. Moreover, phenomenological...

We discuss the model with the modular $A_4$ invariance. It has been shown that this model can explain neutrino masses and mixing angles observed by oscillation experiments. We investigate the leptogenesis in this model. It is found that the leptogenesis by decay of right-handed neutrinos works well. Especially, we show that the Dirac and Majorana CP-phases in the PMNS matrix and right-handed...
