Gluon Gravitational $D$ -Form Factor: The $σ$ -Meson as a Dilaton Confronted with Lattice Data II

Roy Stegeman, Roman Zwicky

We investigate the gluon gravitational form factors of the $π$ , $N$ , $ρ$ , and $Δ$ using lattice QCD data at $m_{π} \approx 450 MeV$ and $m_{π} \approx 170 MeV$ . We base the…

Gravitational $D$ -Form Factor: The $σ$ -Meson as a Dilaton confronted with Lattice Data

Roy Stegeman, Roman Zwicky

We investigate the nucleon and pion gravitational $D$ -form factors, by fitting a $σ / f_{0} (500)$ -meson pole, together with a background term, to lattice data at $m_π\approx 170\text{M…
