Possible galactic sources of ultrahigh-energy cosmic rays and a strategy for their detection via gravitational lensing
Alexander Kusenko, Vadim A. Kuzmin
If decays of superheavy relic particles in the galactic halo are responsible for ultrahigh-energy cosmic rays, these particles must be clustered to account for small-scale anisotro…
Baryonic Q-balls as dark matter
Alexander Kusenko
Supersymmetric extensions of the Standard Model predict the existence of Q-balls, some of which can be entirely stable. Affleck-Dine baryogenesis can result in a copious production…
Signature neutrinos from ultrahigh-energy photons
Alexander Kusenko
At high red shift, the temperature of cosmic microwave background is sufficiently high for the ultrahigh-energy photons to pair-produce muons and pions through interactions with th…
Neutrinos produced by ultrahigh-energy photons at high red shift
Alexander Kusenko, Marieke Postma
Some of the proposed explanations for the origin of ultrahigh-energy cosmic rays invoke new sources of energetic photons (e.g., topological defects, relic particles, etc.). At high…
Cosmology of Q-balls
Alexander Kusenko
Supersymmetric extensions of the Standard Model predict the existence of Q-balls, some of which can be entirely stable. Both stable and unstable Q-balls can play an important role…
Baryon number non-conservation and phase transitions at preheating
John M. Cornwall, Alexander Kusenko
Certain inflation models undergo pre-heating, in which inflaton oscillations can drive parametric resonance instabilities. We discuss several phenomena stemming from such instabili…
