Longitudinal structure function $F_{L}$ at low $Q^{2}$ and low $x$ with model for higher twist: an update

B. Badelek, A. M. Stasto

A reanalysis of the model for the longitudinal structure function $F_{L} (x, Q^{2})$ at low $x$ and low $Q^{2}$ was undertaken, in view of the advent of the EIC. The model is based on the…

Triangle Singularity as the Origin of the $a_{1} (1420)$

G. D. Alexeev, M. G. Alexeev, A. Amoroso +194

The COMPASS experiment recently discovered a new isovector resonance-like signal with axial-vector quantum numbers, the $a_{1} (1420)$ , decaying to $f_{0} (980) π$ . With a mass too close…

New analysis of $η π$ tensor resonances measured at the COMPASS experiment

A. Jackura, C. Fernandez-Ramirez, M. Mikhasenko +232

We present a new amplitude analysis of the $η π$ $D$ -wave in $π^{-} p \to η π^{-} p$ measured by COMPASS. Employing an analytical model based on the principles of the relativistic $S$ -mat…

GVMD model predictions for the low Q^2 behaviour of the spin structure function g_1(x,Q^2) and of the DHGHY integral I(Q^2)

Barbara Badełek, Jan Kwieciński, Beata Ziaja

Predictions for g_1(x,Q^2) at low Q^2 are obtained in the framework of the GVMD model. Contributions from both light and heavy vector mesons are evaluated. The DHGHY sum rule is em…

Spin structure function $g_{1} (x, Q^{2})$ and the DHGHY integral $I (Q^{2})$ at low $Q^{2}$ : predictions from the GVMD model

Barbara Badełek, Jan Kwieciński, Beata Ziaja

Theoretical predictions for polarized nucleon structure function $g_{1} (x, Q^{2})$ at low $Q^{2}$ are obtained in the framework of the Generalized Vector Meson Dominance model. Contributi…
