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…
Scale-anomaly-induced binding pressure in hadrons
Daisuke Fujii, Mitsuru Tanaka
The effect of the QCD scale anomaly on the internal pressure distribution of hadrons is studied based on the trace-traceless decomposition of the energy-momentum tensor. Using rece…
Scalar-glueball-mediated scale-anomaly dominance of the confining pressure of the pion in holographic QCD
Daisuke Fujii, Akihiro Iwanaka, Mitsuru Tanaka
In this work, we analyze the energy density and the stress distribution inside the pion derived from gravitational form factors in top-down holographic QCD. In particular, we show…
Pion Gravitational Form Factors in Holographic QCD
Mitsuru Tanaka, Daisuke Fujii, Akihiro Iwanaka
We present the first calculation of the momentum-transfer dependence of the pion gravitational form factors (GFFs) within a top-down holographic QCD framework. These form factors e…
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…
