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

Roy Stegeman, Roman Zwicky

We investigate the gluon gravitational form factors of the $I ¨ $ , $N$ , $I ¨ $ , and $I^$ using lattice QCD data at $m_{I ¨} \approx 450 MeV$ and $m_{I ¨} \approx 170 MeV$ . We bas…

Gravitational $D$ -Form Factor: The $I ¨ $ -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 $I ¨ / f_{0} (500)$ -meson pole, together with a background term, to lattice data at $m_Ï\approx 170\text…

Soft Theorems and Dilaton Effective Theory

Roman Zwicky

We derive a new model-independent double-soft dilaton theorem, taking into account the spacetime dependence of the dilation commutator $[i Q_D,{\cal O}(x)]= (Î_{\cal O} + x \cdot…
