Significance of soft-scale breaking on primordial black hole production in Coleman-Weinberg type supercooling-phase transition
He-Xu Zhang, Katsuya Hashino, Hiroyuki Ishida +1
Ultra-supercooling phase transitions can generate large overdensities in the Universe, potentially leading to the formation of primordial black holes (PBHs), which can also be a da…

Dark QCD perspective inspired by strong CP problem at QCD scale
Bin Wang, Shinya Matsuzaki, Hiroyuki Ishida
We discuss a QCD-scale composite axion model arising from dark QCD coupled to QCD. The presently proposed scenario not only solves the strong CP problem, but also is compatible wit…
