Kaon gravitational form factors and mechanical structure in a three-flavor NJL model
Zhibo Liu, Hiroaki Abuki
We investigate the gravitational form factors (GFFs) of the kaon in a proper-time-regularized three-flavor Nambu--Jona-Lasinio model. We treat the kaon as a light--strange pseudosc…

Pion and kaon D terms from holographic QCD and coupled-channel dispersion relations
Zhibo Liu
For a spin-zero meson, the exact trace identity relates the D term to the tensor gravitational form factor and the total scalar trace . We study the pion and kaon…
