Title: Probing the properties of neutrinos and the mechanism behind the baryon
asymmetry
With neutrino oscillations pointing us towards massive neutrinos, they
are a clear hint towards physics beyond the standard model. With a
bright and diverse landscape of current and future experiments, novel
approaches are being developed to probe the nature and interactions of
neutrinos. First, I will talk about possible dim-5 interactions, in
particular transition magnetic moments, and will discuss the sensitivity
of coherent elastic neutrino-nucleus scattering experiments to probe
those. In this context, I will present a new smoking gun signature that
can probe sterile neutrinos in an unexplored parameter space and can be
used to distinguish between a Dirac or Majorana nature. I will then
continue with possible dim-7 and dim-9 lepton-number violating
interactions. I will discuss the interesting interplay between different
observables such as meson decays, neutrinoless double beta decay and LHC
searches. Finally, I will demonstrate the far-reaching implications of
such an observation for cosmology: the potential to render standard
thermal leptogenesis unviable.
