Baryon number freeze-out in the Standard Model, precisely
Cristina Benso, Dietrich Bödeker, Kohei Kamada +4
Weak sphaleron transitions turn a lepton asymmetry of the Standard Model plasma in the early Universe into a baryon asymmetry, conserving baryon-minus-lepton number and its i…
Cosmological constraints on TeV-scale dark matter subcomponents decaying between recombination and reionisation
Markus R. Mosbech, Cristina Benso, Felix Kahlhoefer
The Dark Ages and the Cosmic Dawn are an untapped well of information about the particle physics properties of dark matter, which may become accessible with future radio telescopes…
Dark matter phase-in: producing feebly-interacting particles after a first-order phase transition
Cristina Benso, Felix Kahlhoefer, Henda Mansour
The freeze-in mechanism describes the out-of-equilibrium production of dark matter (DM) particles via feeble couplings or non-renormalisable interactions with large suppression sca…
Large neutrino mass in cosmology and keV sterile neutrino dark matter from a dark sector
Cristina Benso, Thomas Schwetz, Drona Vatsyayan
We consider an extended seesaw model which generates active neutrino masses via the usual type-I seesaw and leads to a large number of massless fermions as well as a sterile neutri…
Sterile neutrino dark matter production in presence of non-standard neutrino self-interactions: an EFT approach
Cristina Benso, Werner Rodejohann, Manibrata Sen +1
Sterile neutrinos with keV-scale masses are popular candidates for warm dark matter. In the most straightforward case they are produced via oscillations with active neutrinos. We i…
Prospects for Finding Sterile Neutrino Dark Matter at KATRIN
Cristina Benso, Vedran Brdar, Manfred Lindner +1
We discuss under what circumstances a signal in upcoming laboratory searches for keV-scale sterile neutrinos would be compatible with those particles being a sizable part or all of…
