Quadratic WIMP-ALP coupling induces coherent freeze-out that allows WIMP annihilation cross sections up to 1000 times larger than standard while matching relic density, plus an ALP miracle where Planck-suppressed couplings naturally yield correct ALP dark matter abundance independent of initial mass

Collapsing axion-like domain walls generate the baryon asymmetry by acting as an effective chemical potential through coupling to the electroweak topological term, with the asymmetry produced via sphaleron processes.
The r0 symmetry is preserved at one-loop in the r0-invariant two-Higgs Doublet Model if the UV cutoff squared transforms non-trivially under r0; the minimal model requires two real fields.
