Particle Production via Rippled Bubble Walls
Ryusuke Jinno, Shota Nakagawa, Yuichiro Nakai +1
The paper studies how spatial ripples on ultra‑relativistic thick bubble walls during a first‑order phase transition can boost the non‑thermal production of heavy particles, introd…
Exploring the Landscape of Spontaneous CP Violation in Supersymmetric Theories
Fangchao Liu, Shota Nakagawa, Yuichiro Nakai +1
The strong CP problem remains one of the most important unresolved issues in the Standard Model. Spontaneous CP violation (SCPV) is a promising approach to the problem by assuming…
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…
Note on Warped Compactification -- Finite Brane Potentials and Non-Hermiticity --
Sudhakantha Girmohanta, Yuichiro Nakai, Motoo Suzuki +2
We study radius stabilization in the Randall-Sundrum model without assuming any unnaturally large stabilizing scalar potential parameter at the boundary branes () by the freque…
