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…
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…
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…
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 wo…
Gauge covariant neural network for quarks and gluons
Yuki Nagai, Akio Tomiya
We propose gauge-covariant neural networks along with a specialized training algorithm for lattice QCD, designed to handle realistic quarks and gluons in four-dimensional space-tim…
