Schwinger dark matter production
Mar Bastero-Gil, Paulo B. Ferraz, Lorenzo Ubaldi +1
Building on recently constructed inflationary vector dark matter production mechanisms as well as studies of magnetogenesis, we show that an inflationary dark Schwinger mechanism c…
Super heavy dark matter from inflationary Schwinger production
Mar Bastero-Gil, Paulo B. Ferraz, Lorenzo Ubaldi +1
We consider a simple setup with a dark sector containing dark electrons charged under an abelian gauge symmetry. We show that if the massless dark photon associated to the…
Analytic false-vacuum decay rate in the thin-wall approximation
Marco Matteini, Miha Nemevšek, Lorenzo Ubaldi
We present a fully analytical calculation of the false vacuum decay rate for a self-interacting scalar field in the thin-wall approximation. We obtain the bounce solution, together…
