One-Loop Charge-Breaking Minima in the Two-Higgs Doublet Model
Pedro M. Ferreira, Logan A. Morrison, Stefano Profumo
We analyze the vacuum structure of the one-loop effective potential in the two Higgs doublet model. We find that electroweak-breaking vacuua can coexist with charge breaking ones,…

Melanopogenesis: Dark Matter of (almost) any Mass and Baryonic Matter from the Evaporation of Primordial Black Holes weighing a Ton (or less)
Logan Morrison, Stefano Profumo, Yan Yu
The evaporation of primordial black holes with a mass in the 1000 kg range can lead to the production of dark matter particles of almost…
