| Title: |
Echoes of supersymmetry from the early universe: baryons, dark
matter, and gravitational waves.
|
| 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.
