A quality-coupling relation in chiral $U (1)_{B - L}$ axion model

Yu-Cheng Qiu

The quality of the QCD axion can be protected by a gauge symmetry. This work considers a gauged chiral $U (1)_{B - L}$ . The vacuum expectation values of two complex scalars break $U(1…

High Reheating Temperature without Axion Domain Walls

Shota Nakagawa, Yuichiro Nakai, Yu-Cheng Qiu +2

We investigate a cosmological scenario in which the Peccei-Quinn (PQ) symmetry remains broken in the entire history of the Universe, thereby avoiding the formation of axion strings…
