Primordial black holes as a probe of strongly first-order electroweak phase transition
Katsuya Hashino, Shinya Kanemura, Tomo Takahashi
Primordial black holes can be produced by density fluctuations generated from delayed vacuum decays of first-order phase transition. The primordial black holes generated at the ele…
Dark matter transient annihilations in the early Universe
Katsuya Hashino, Jia Liu, Xiao-Ping Wang +1
The cosmological evolution can modify the dark matter (DM) properties in the early Universe to be vastly different from the properties today. Therefore, the relation between the re…
Electroweak phase transition triggered by fermion sector
Qing-Hong Cao, Katsuya Hashino, Xu-Xiang Li +2
To realize first-order electroweak phase transition, it is necessary to generate a barrier in the thermal Higgs potential, which is usually triggered by scalar degree of freedom. W…
