Title: Echoes of supersymmetry from the early universe: baryons, dark matter, and gravitational waves. [PDF]
Abstract: Supersymmetry and inflation combined create the conditions in the early universe for Affleck-Dine baryogenesis, which can give rise to the matter-antimatter asymmetry, as well as to dark matter in the form of SUSY Q-balls. The fragmentation of the condensate into lumps (Q-balls) can also produce gravity waves at the level detectable by Laser Interferometer Space Antenna (LISA), Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), and Big Bang Observer (BBO). An observation of such a signal can offer an important window on the early universe and the physics at some very high energy scales.
