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…
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…
