Transient Bias for CP Domain Wall Decay and Dark Matter
Sally Yuxuan Hao, Fangchao Liu, Shota Nakagawa +1
Spontaneous CP violation (SCPV) provides an attractive solution to the strong CP problem. However, SCPV after inflation suffers from the formation of CP domain walls, requiring the…

Bias with a Timer: Axion Domain Wall Decay and Dark Matter
Sally Yuxuan Hao, Shota Nakagawa, Yuichiro Nakai +1
We explore the interplay of the post-inflationary QCD axion and a light scalar field for the axion domain wall decay and dark matter (DM). The scalar field possesses a nonzero vacu…
