Probing sterile neutrino freeze-in at stronger coupling
Niko Koivunen, Oleg Lebedev, Martti Raidal
The regime of dark matter (DM) freeze-in at stronger coupling interpolates between freeze-in and freeze-out. It relies on Boltzmann-suppressed dark matter production, implying that…

Production and decays of 146 GeV flavons into final state at the LHC
Niko Koivunen, Martti Raidal
The CMS experiment at CERN has reported a possible signal for a resonance at 146 GeV decaying into the final state which, presently, is the only experimental hint for lepton f…
