Particle Production via Rippled Bubble Walls
Ryusuke Jinno, Shota Nakagawa, Yuichiro Nakai +1
We investigate non-thermal particle production during first-order phase transitions in the presence of ultra-relativistic thick bubble walls with non-trivial internal structure. Ex…
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…
Spontaneous CP violation in Supersymmetric QCD
Shota Nakagawa, Yuichiro Nakai, Yaoduo Wang
We investigate a composite model of spontaneous CP violation based on a new supersymmetric QCD as a solution to the strong CP problem. The scalar components of the meson chiral sup…
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 frequen…
