Cosmological Roles of Dark Photons in Axion-induced Electroweak Baryogenesis
Kwang Sik Jeong, Ju Hyeong Kang, Shota Nakagawa
By coupling to both the Higgs and electroweak gauge sectors, an axion can generate the matter-antimatter asymmetry in the universe via electroweak baryogenesis when the axion decay…

Dissipation of axion energy via the Schwinger and Witten effects
Kwang Sik Jeong, Shota Nakagawa, Fuminobu Takahashi +1
In the presence of an anomalous CP phase in a U(1) gauge theory, a monopole becomes a dyon via the Witten effect. When the anomalous CP phase is promoted to a dynamical field, the…
