Ultralight pion and superheavy baryon dark matter

We consider a dark confining gauge theory with millicharged ultralight pions (ULP) and heavy baryons as matter candidates. The model simultaneously realizes the (strongly interacting particle or ``STUMP'') superheavy (``WIMPzilla'') paradigms, connected by confinement scale of QCD. It is realization matter, unlike conventional axions, exhibits mass splitting between charged neutral pions. ULPs can easily provide observed density be cosmologically stable, for broad range QCD scales quark masses. baryons, produced via gravitational production freeze-in, an additional contribution to density. Dark halos boson stars in this context are generically admixture three leading diversity profiles. That opens up accessible parameter space compared standard scenarios probed future experiments. briefly discuss interesting phenomenology, such ULP electrodynamics, cosmic backgrounds.
