Flavour and cosmological probes of Diracon models
Salvador Centelles Chuliá, Tim Herbermann, Antonio Herrero-Brocal +1
We present and analyze two minimal extensions of the Standard Model featuring a spontaneously broken global, chiral, and anomaly-free symmetry. This breaking generates nat…

Improved cosmological limits on models with light right-handed neutrinos
Tim Herbermann, Manfred Lindner
We improve limits on extensions of the Standard Model (SM) with light right-handed neutrinos. The presence of shared gauge interactions between the light right-handed ne…

Attenuation of Cosmic Ray Electron Boosted Dark Matter
Tim Herbermann, Manfred Lindner, Manibrata Sen
We consider a model of boosted dark matter (DM), where a fraction of DM is upscattered to relativistic energies by cosmic ray electrons. Such interactions responsible for boosting…
