Matter asymmetry sourced dark matter

We investigate the possibility that dark matter abundance is sourced by baryon/lepton asymmetry of early Universe. It turns out a Goldstone field local classically preserved symmetry in Standard Model experiences kick during period number generation. This mechanism can be regarded as dynamical generation initial conditions for misalignment yet prediction relic presents an inverse dependence on coupling parallel with freeze-in vs freeze-out. explore two realizations this and show conjunction leptogenesis, it possible to identify viable promising region parameter space production mass 10 MeV - 1 GeV decay constant f range $10^{10} 10^{12}$ GeV.
