Gravitational waves from Affleck-Dine condensate fragmentation

Understand

We compute the stochastic gravitational wave production from Affleck-Dine condensate fragmentation in the early universe, focusing on an effective potential with a logarithmic mass correction that typically arises in gravity mediated supersymmetry breaking scenarios.

• We find that a significant gravitational wave background can be generated when Q-balls are being formed out of the condensate fragmentation.
• This gravitational wave background has a distinct multi-peak power spectrum where the trough is closely linked to the supersymmetry breaking scale and whose frequencies are peaked around kHz for TeV supersymmetry breaking.
