Properties and signatures of supersymmetric Q-balls
Alexander Kusenko
Supersymmetric extensions of the Standard Model predict the existence of Q-balls with baryon and lepton numbers. Stable Q-balls can form at the end of inflation from the fragmentat…
Sterile dark matter and reionization
Alexander Kusenko
Sterile neutrinos with masses in the keV range can be the dark matter, and their emission from a supernova can explain the observed velocities of pulsars. The sterile neutrino deca…
Sterile neutrinos, dark matter, and the pulsar velocities in models with a Higgs singlet
Alexander Kusenko
We identify the range of parameters for which the sterile neutrinos can simultaneously explain the cosmological dark matter and the observed velocities of pulsars. To satisfy all c…
Detecting sterile dark matter in space
Alexander Kusenko
Space-based instruments provide new and, in some cases, unique opportunities to search for dark matter. In particular, if dark matter comprises sterile neutrinos, the x ray detecti…
A-term inflation and the smallness of the neutrino masses
Rouzbeh Allahverdi, Alexander Kusenko, Anupam Mazumdar
The smallness of the neutrino masses may be related to inflation. The minimal supersymmetric Standard Model (MSSM) with small Dirac neutrino masses already has all the necessary in…
Thermal evolution of the primordial clouds in warm dark matter models with keV sterile neutrinos
Jaroslaw Stasielak, Peter L. Biermann, Alexander Kusenko
We analyze the processes relevant for star formation in a model with dark matter in the form of sterile neutrinos. Sterile neutrino decays produce an X-ray background radiation tha…
Relic keV sterile neutrinos and reionization
Peter L. Biermann, Alexander Kusenko
A sterile neutrino with mass of several keV can account for cosmological dark matter, as well as explain the observed velocities of pulsars. We show that X-rays produced by the dec…
Opening a new window for warm dark matter
Takehiko Asaka, Mikhail Shaposhnikov, Alexander Kusenko
We explore the range of parameters for dark-matter sterile neutrinos in an extention of the Minimal Standard Model by three singlet fermions with masses below the electroweak scale…
