Gravitational waves can affect neutrino oscillation probabilities and
may hence be detectable at neutrino telescopes. We propose a heuristic
model describing the influence of gravitational waves on the propagation
and flavor oscillations of neutrino wave packets.
This model is based on the assumption that at lowest order in the
metric perturbation caused by the gravitational wave only the...
The smallness of neutrino masses in the inverse seesaw mechanism arises due to the interplay of TeV-scale Pseudo-Dirac mass terms and a small explicit breaking of lepton number. Here we propose to use dynamical symmetry breaking from a confining dark non-abelian symmetry to explain such a small lepton-number breaking mass. We couple a single generation of vector-like dark quarks,...
In this study conducted under a freeze-out scenario, we examine a scotogenic model that tackles the dark matter problem while simultaneously producing three non-zero neutrino masses. Our investigation delves into the dual nature of a dark matter candidate, manifesting from distinct particle components across various energy regimes within the HL-LHC energy range. The results shed light on the...
We present a model which addresses two open questions of the Standard Model (SM): the origin of neutrino masses and the nature of dark matter. To achieve this, the SM is extended by two keV-mass right-handed neutrinos as well as a Froggatt-Nielsen-like mechanism, under which only the non-SM fields are charged.
The sterile neutrinos form a 2-component dark matter candidate. We assume the...
In this talk, I will discuss the freeze-in dark matter production mechanism at low reheating temperatures. The process is Boltzmann-suppressed if the dark matter mass is above the reheating temperature, and, in this case, the coupling to the thermal bath has to be significant to account for the observed dark matter relic density. As a result, the direct DM detection experiments can already...
