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…
Walking-dilaton hybrid inflation with Higgs embedded in dynamical scalegenesis
Jie Liu, He-Xu Zhang, Hiroyuki Ishida +1
We propose a hybrid inflationary scenario based on eight-flavor hidden QCD with the hidden colored fermions being in part gauged under . This hidden QCD is almost scale…
Gravitational wave footprints from Higgs-portal scalegenesis with multiple dark chiral scalars
He-Xu Zhang, Shinya Matsuzaki, Hiroyuki Ishida
We discuss the gravitational wave (GW) spectra predicted from the electroweak scalegenesis of the Higgs portal type with a large number of dark chiral flavors, which many flavor QC…
Dynamical realization of the small field inflation of Coleman-Weinberg type in the post supercooled universe
He-Xu Zhang, Hiroyuki Ishida, Shinya Matsuzaki
The small field inflation (SFI) of Coleman-Weinberg (CW) type suffers from precise tuning of the initial inflaton field value to be away from the true vacuum one. We propose a dyna…
QCD preheating: New frontier of baryogenesis
Xin-Ru Wang, Jin-Yang Li, Seishi Enomoto +2
We find that QCD can create the cosmological matter abundance via out-of-equilibrium processes during the QCD phase transition, that is what we call the QCD preheating, where the d…
QCD knows new quarks
Chuan-Xin Cui, Hiroyuki Ishida, Mamiya Kawaguchi +3
We find that a big gap between indicators for the breaking strengths of the global chiral SU(2) and U(1) axial symmetries in QCD of the Standard Model (SM) can be interpreted as a…
