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…
The effect of charm quark on the QCD chiral phase diagram
Fei Gao, Yuepeng Guan, Shinya Matsuzaki
We study the influence of charm-quark dynamics on the chiral phase structure of Quantum Chromodynamics (QCD) using the recently developed miniDSE scheme for the Dyson-Schwinger equ…
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…
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…
