Neutrino Self-Interactions
Jasper Hasenkamp
We propose a theory that equips the active neutrinos with interactions among themselves that are at least three orders of magnitude stronger than the weak interaction. We introduce…
LHC constraints on Gravitino Dark Matter
Alexandre Arbey, Marco Battaglia, Laura Covi +2
Gravitino Dark Matter represents a compelling scenario in Supersymmetry, which brings together a variety of data from cosmology and collider physics. We discuss the constraints obt…
Daughters mimic sterile neutrinos (almost!) perfectly
Jasper Hasenkamp
Since only recently, cosmological observations are sensitive to hot dark matter (HDM) admixtures with sub-eV mass, < eV, that are not fully-thermalised, $…
Tight bonds between sterile neutrinos and dark matter
Torsten Bringmann, Jasper Hasenkamp, Joern Kersten
Despite the astonishing success of standard CDM cosmology, there is mounting evidence for a tension with observations at small and intermediate scales. We introduce a simple mod…
NMSSM with Gravitino Dark Matter to be tested at LHC
Jasper Hasenkamp, Martin Wolfgang Winkler
We present a solution to the gravitino problem, which arises in the NMSSM, allowing for sparticle spectra from ordinary gravity-mediated supersymmetry breaking with weak-scale grav…
A new life for sterile neutrinos: resolving inconsistencies using hot dark matter
Jan Hamann, Jasper Hasenkamp
Within the standard LCDM model of cosmology, the recent Planck measurements have shown discrepancies with other observations, e.g., measurements of the current expansion rate H_0,…
