phase structure of QCD from functional renormalization group
Yuepeng Guan, Shinya Matsuzaki, Masatoshi Yamada
We study the low-energy properties of QCD-like theories in the presence of a -odd and axial breaking four-fermion operator $\left( \barψ ψ\right) \left( \barψ i γ_5 ψ\rig…
Thermodynamics in symmetry-improved Cornwall-Jackiw-Tomboulis formalism: application to the low-energy effective theory of QCD
Yuepeng Guan, Mamiya Kawaguchi, Shinya Matsuzaki +1
We study the thermodynamics of the symmetry-improved Cornwall-Jackiw-Tomboulis (SICJT) formalism and apply it to a low-energy effective theory of QCD. In the symmetry-improved form…
Columbia plot based on symmetry-improved CJT formalism in linear sigma model
Yuepeng Guan, Mamiya Kawaguchi, Shinya Matsuzaki +1
We study the Columbia plot for the chiral phase transition in the framework of a three-flavor linear sigma model based on the Cornwall-Jackiw-Tomboulis (CJT) formalism. The convent…
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…
Axionlike particle-assisted supercooling chiral phase transition in QCD: Identifying Coleman-Weinberg type-chiral phase transition in QCD-like scenarios
Zheng-liang Jiang, Yuepeng Guan, Mamiya Kawaguchi +3
We propose a new scenario to realize the Coleman-Weinberg (CW) type chiral phase transition in the QCD thermal history. This scenario predicts a heavy axionlike particle (ALP) with…
First-order CP phase transition in two-flavor QCD at under electromagnetic scale anomaly via a Nambu-Jona-Lasinio description
Yuanyuan Wang, Shinya Matsuzaki, Mamiya Kawaguchi +1
We discuss the thermal CP phase transition in QCD at under a weak magnetic field background, where the electromagnetic scale anomaly gets significant. To explicitize, we work…
Spacetime and Planck mass generation from scale-invariant degenerate gravity
Yadikaer Maitiniyazi, Shinya Matsuzaki, Kin-ya Oda +1
We investigate a gravitational model based on local Lorentz invariance and general coordinate invariance. The model incorporates classical scale invariance, which forbids dimension…
Functional renormalization group study of a four-fermion model with violation
Linlin Huang, Mamiya Kawaguchi, Yadikaer Maitiniyazi +3
We perform a functional renormalization group analysis of a four-fermion model with and violation to explore the nonperturbative infrared dynamics of quantum chromodynamic…
Implications of electromagnetic scale anomaly to QCD chiral phase transition in smaller quark mass regime: does not drop with eB
Yuanyuan Wang, Mamiya Kawaguchi, Shinya Matsuzaki +1
The decrease of the chiral pseudocritical temperature with an applied strong magnetic field has been extensively investigated by various QCD low-energy effective…
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…
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…
Baryogenesis via QCD preheating with nonadiabatic baryon chemical potential
Jimin Wang, Xin-Ru Wang, Shinya Matsuzaki
The chiral phase transition in QCD can be supercooled in the thermal history of the universe to be instantaneously out-of equilibrium, if QCD is coupled to a dark QCD sector exhibi…
Ladder top-quark condensation imprints in supercooled electroweak phase transition
Yuepeng Guan, Shinya Matsuzaki
The electroweak (EW) phase transition in the early Universe might be supercooled due to the presence of the classical scale invariance involving Beyond the Standard Model (BSM) sec…
Impact of local CP-odd domain in hot QCD on axionic domain-wall interpretation for NANOGrav 15-year Data
Linlin Huang, Yuanyuan Wang, He-Xu Zhang +4
We argue that the axionic domain-wall with a QCD bias may be incompatible with the NANOGrav 15-year data on a stochastic gravitational wave (GW) background, when the domain wall ne…
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…
Irreversible vierbein postulate: Emergence of spacetime from quantum phase transition
Yadikaer Maitiniyazi, Shinya Matsuzaki, Kin-ya Oda +1
We formulate a model for quantum gravity based on the local Lorentz symmetry and general coordinate invariance. A key idea is the irreversible vierbein postulate that a tree-level…
