      Analysis

      This paper introduces a novel machine-learning method using neural networks to extract Generalized Parton Distributions (GPDs) from experimental data. The method addresses the challenging inverse problem of relating Compton Form Factors (CFFs) to GPDs, incorporating physical constraints like the QCD kernel and endpoint suppression. The approach allows for a probabilistic extraction of GPDs, providing a more complete understanding of hadronic structure. This is significant because it offers a model-independent and scalable strategy for analyzing experimental data from Deeply Virtual Compton Scattering (DVCS) and related processes, potentially leading to a better understanding of the internal structure of hadrons.
      Reference

      The method constructs a differentiable representation of the Quantum Chromodynamics (QCD) PV kernel and embeds it as a fixed, physics-preserving layer inside a neural network.

        Analysis

        This paper investigates the color correlations between static quarks in multiquark systems (3Q and 4Q) using lattice QCD. Understanding these correlations is crucial for understanding the strong force and the behavior of hadrons. The study's focus on the dependence of color correlations on the spatial configuration of quarks, particularly the flux tube path length, provides valuable insights into the dynamics of these systems. The finding of "universality" in the color leak across different multiquark systems is particularly significant.
        Reference

        The color correlations depend on the minimal path length along a flux tube which connects two quarks under consideration. The color correlation between quarks quenches because of color leak into the gluon field (flux tube) and finally approaches the random color configuration in the large distance limit. We find a ``universality'' in the flux-tube path length dependence of the color leak for 2Q, 3Q, and 4Q ground-state systems.
