Dark Matter and Baryogenesis from Visible-Sector Long-Lived Particles
Rouzbeh Allahverdi, Ngo Phuc Duc Loc, Jacek K. Osiński
We present a minimal extension of the standard model that includes a long-lived fermion with weak-scale mass and an fermionic dark matter candidate both of wh…
Dark matter production through a non-thermal flavon portal
Andrew Cheek, Jacek K. Osiński, Leszek Roszkowski +1
The Froggatt-Nielsen (FN) mechanism provides an attractive way of generating the determined fermion mass hierarchy and quark mixing matrix elements in the Standard Model (SM). Here…
Dark Matter Axions in the Early Universe with a Period of Increasing Temperature
Paola Arias, Nicolás Bernal, Jacek K. Osiński +1
We consider the production of axion dark matter through the misalignment mechanism in the context of a nonstandard cosmological history involving early matter domination by a scala…
