With the establishment and maturation of the experimental programs searching for new
physics with sizeable couplings at the LHC, there is an increasing interest in the broader …

The Majorana nature of neutrinos is strongly motivated from the theoretical and
phenomenological point of view. A plethora of neutrino mass models, known collectively as …

The observation of neutrinoless double beta decay (DBD) will have important
consequences. First it will signal that lepton number is not conserved and the neutrinos are …

We for the first time map the range of active-sterile neutrino mixing angles in which
leptogenesis is possible in the type I seesaw model with three heavy neutrinos with …

The extension of the Standard Model by right-handed neutrinos can not only explain the
active neutrino masses via the seesaw mechanism, it is also able solve a number of long …

The sensitivity of beam dump experiments to heavy neutral leptons depends on the relative
strength of their couplings to individual lepton flavours in the Standard Model. We study the …

This report summarizes the present status of neutrino non-standard interactions (NSI). After
a brief overview, several aspects of NSIs are discussed, including connection to neutrino …

A bstract We revisit the production of baryon asymmetries in the minimal type I seesaw
model with heavy Majorana singlets in the GeV range. In particular we include “washout” …

A bstract We investigate the question whether leptogenesis, as a mechanism for explaining
the baryon asymmetry of the universe, can be tested at future colliders. Focusing on the …

The focus of this paper lies on the possible experimental tests of leptogenesis scenarios. We
consider both leptogenesis generated from oscillations, as well as leptogenesis from out-of …
