Kick-alignment: matter asymmetry sourced dark matter |
|
Résumé |
We investigate the possibility that the dark matter abundance is sourced by the
baryon/lepton asymmetry of the early Universe. In our realization the Goldstone
field of a local classically preserved symmetry of the Standard Model experiences
a kick during a period of baryon/lepton number generation. This mechanism can be
regarded as dynamical generation of initial conditions for misalignment yet the
prediction for relic abundance presents an inverse dependence on the coupling in
parallel with freeze-in vs freeze-out. In conjunction with lepto-genesis, we
identify a viable region of parameter space for dark matter production with mass
10 MeV - 1 GeV and decay constant f in the range $10^{10}-10^{12} GeV$. |
