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…
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…
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…
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…
Fate of the first-order chiral phase transition in QCD: Implications for dark QCD studied via a Nambu-Jona-Lasinio model
Yuanyuan Wang, Mamiya Kawaguchi, Shinya Matsuzaki +1
The first-order nature of the chiral phase transition in QCD-like theories can play crucial roles to address a dark side of the Universe, where the created out-of equilibrium is es…
New aspect of chiral and axial breaking in QCD
Chuan-Xin Cui, Mamiya Kawaguchi, Jin-Yang Li +2
Violation of the axial symmetry in QCD is stricter than the chiral breaking, simply because of the presence of the quantum axial anomaly. If the QCD gauge coupling i…
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…
New interpretation of chiral phase transition: Violation of trilemma in QCD
Chuan-Xin Cui, Jin-Yang Li, Shinya Matsuzaki +2
We find that the chiral phase transition (chiral crossover) in QCD at physical point is triggered by big imbalance among three fundamental quantities essential for the QCD vacuum s…
Detecting scale anomaly in chiral phase transition of QCD: new critical endpoint pinned down
Mamiya Kawaguchi, Shinya Matsuzaki, Akio Tomiya
Violation of scale symmetry, scale anomaly, being a radical concept in quantum field theory, is of importance to comprehend the vacuum structure of QCD, and should potentially cont…
Analysis on nonperturbative flavor violation at chiral crossover criticality in QCD
Mamiya Kawaguchi, Shinya Matsuzaki, Akio Tomiya
We discuss the violation of quark-flavor symmetry at high temperatures, induced from nonperturbative thermal loop corrections and axial anomaly, based on a three-flavor linear-sigm…
Nonperturbative Flavor Breaking in Topological Susceptibility at Chiral Crossover
Mamiya Kawaguchi, Shinya Matsuzaki, Akio Tomiya
We demonstrate that the QCD topological susceptibility nonperturbatively gets a significant contribution signaled by flavor-nonuniversal quark condensates at around the pseudo-crit…
