Supersymmetric Q-balls as dark matter
read the original abstract
Supersymmetric extensions of the standard model generically contain stable non-topological solitons, Q-balls, which carry baryon or lepton number. We show that large Q-balls can be copiously produced in the early universe, can survive until the present time, and can contribute to dark matter.

Kaon Portal to Freeze-in Dark Matter
Freeze-in dark matter produced by kaons in low-reheating cosmologies requires larger couplings at lower reheating temperatures, directly linking the relic density to observable rates in rare kaon decay experiments.

Dynamical flattening of halo density cusps by Q-ball dark matter
Interacting Q-ball dark matter flattens NFW cusps via density-dependent mergers that convert rest mass into escaping relativistic dark-sector particles, preferentially in halo centers.

Gauged Q-balls in flat potentials
Gauged Q-balls in flat potentials are qualitatively similar to thin-wall versions, with analytic approximations matching numerics and Proca Q-balls interpolating between global and gauged regimes.
