A ménage à trois of eV-scale sterile neutrinos, cosmology, and structure formation
Basudeb Dasgupta, Joachim Kopp
We show that sterile neutrinos with masses ~1 eV or larger, as motivated by several short-baseline oscillation anomalies, can be consistent with cosmological constraints if they ar…
Constraints on dark matter annihilation from AMS-02 results
Joachim Kopp
We use recently released data on the positron-to-electron ratio in cosmic rays from the AMS-02 experiment to constrain dark matter annihilation in the Milky Way. Due to the yet une…
Sterile Neutrino Oscillations: The Global Picture
Joachim Kopp, Pedro A. N. Machado, Michele Maltoni +1
Neutrino oscillations involving eV-scale neutrino mass states are investigated in the context of global neutrino oscillation data including short and long-baseline accelerator, rea…
From gamma ray line signals of dark matter to the LHC
Joachim Kopp, Ethan T. Neil, Reinard Primulando +1
We explore the relationship between astrophysical gamma-ray signals and LHC signatures for a class of phenomenologically successful secluded dark matter models, motivated by recent…
