Mass distribution of magnetized quark-nugget dark matter and comparison with requirements and observations.

ABSTRACT: Quark nuggets are a candidate for dark matter consistent with the Standard Model. Previous models of quark nuggets have investigated properties arising from their being composed of strange, up, and down quarks and have not included any effects caused by their self-magnetic field. However, Tatsumi found that the core of a magnetar star may be a quark nugget in a ferromagnetic state with core magnetic field B_surface = 10^12±1 T. We apply Tatsumi's result to quark-nugget dark-matter and report results on aggregation of magnetized quark nuggets (MQNs) after formation from the quark-gluon plasma until expansion of the universe freezes out the mass distribution to ~ 10^-24 kg to ~ 10¹⁴ kg. Aggregation overcomes weak-interaction decay. Computed mass distr
