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…
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( \barÏ Ï\right) \left( \barÏ i γ_5 Ï…
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…
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…
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…
