Thermalization and hotspot formation around small primordial black holes
Minxi He, Kazunori Kohri, Kyohei Mukaida +1
We quantitatively analyze a basic question: what is the stationary solution of the background plasma temperature profile around a black hole (BH)? One may naively expect that the t…

Thermal Wash-in Leptogenesis via Heavy Higgs Decay
Kyohei Mukaida, Hidenaga Watanabe, Masaki Yamada
We present a conceptually simple model to generate asymmetries that are not directly related to baryon nor lepton charges. The model employs a three-Higgs doublet framework, wherei…
