Charmonium-nucleon femtoscopy as a possible probe of the nucleon gravitational form factor

Ren Ejima, Daisuke Fujii, Mamiya Kawaguchi

We investigate the charmonium-nucleon interaction, focusing on its connection with the internal structure of the nucleon encoded in the gravitational form factors. To describe this…

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…

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…

Probing the chiral and axial symmetry restoration via meson susceptibilities in holographic QCD

Hiwa A. Ahmed, Danning Li, Mamiya Kawaguchi +1

We investigate the restoration patterns of chiral and axial symmetries at finite temperature using a soft-wall holographic QCD model. The study employs two distinct paramete…

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…
