Origin of hadron mass from gravitational D-form factor and neutron star measurements
Mamiya Kawaguchi, Masayasu Harada, Yong-Liang Ma
Clarifying the origin of hadron mass is one of the fundamental problems in particle physics, relevant from hadronic scales to astrophysical observations. At low energies, this issu…
Gravitational form factors of the nucleon from the chiral effective model
Daisuke Fujii, Mamiya Kawaguchi, Mitsuru Tanaka
We investigate the confining pressure and associated global property, i.e, D-term, of the nucleon using the skyrmion approach formulated within scale-invariant chiral perturbation…
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…
Gravitational form factors of the nucleon in the Skyrme model based on scale-invariant chiral perturbation theory
Mitsuru Tanaka, Daisuke Fujii, Mamiya Kawaguchi
We investigate the role of the QCD scale anomaly in the gravitational form factors of the nucleon -- particularly the form factor -- as well as the associated stress distrib…
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…
Susceptibilities of rotating quark matter in Fourier-Bessel basis
Mamiya Kawaguchi, Kazuya Mameda
We analyze various two-point correlation functions of fermionic bilinears in a rotating finite-size cylinder at finite temperatures, with a focus on susceptibility functions. Due t…
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…
Dominance of gluonic scale anomaly in confining pressure inside nucleon and D-term
Daisuke Fujii, Mamiya Kawaguchi, Mitsuru Tanaka
We explore the confining pressure inside the nucleon and the related gravitational form factor referred to as the D-term, using the skyrmion approach based on the scale-invariant c…
