Summary: Observable measures provide clear windows into emergent hadron mass and its modulations by Higgs boson interactions, which can be accessed through generalised parton distributions (GPDs). Analysis reveals various properties and predictions, such as stiffness differences between gravitational and electromagnetic form factors, tightness of K pressure profiles compared to pi profiles, and similar fraction of meson mass-squared carried by glue and sea combined as with the valence degrees-of-freedom.

Summary: The analysis of the pion valence-quark distribution function predicts that its behavior at x approximately equal to 1 follows the model of (1 - x)(β(σ)), taking into account the pion wave function prescribed by QCD. However, the empirical status of this behavior remains uncertain due to disagreements in fitting existing data. Further experimental data is needed to reach a final conclusion.

Summary: The MARATHON experiment determines the ratio of the nucleon F-2 structure functions, F-2(n)/F-2(p), through measurements of deep inelastic scattering of electrons from H-3 and He-3 nuclei. The experiment achieves significant improvements compared to previous measurements and compares the results to theoretical calculations and empirical determinations of the ratio.

Summary: In the past decade, there has been a significant shift in understanding the internal structure of hadrons, with new theoretical techniques and experimental findings suggesting that soft quark+quark (diquark) correlations play a crucial role in hadron physics. These correlations are believed to be a necessary consequence of dynamical chiral symmetry breaking and may be critical for the formation of exotic tetra- and penta-quark hadrons.

Summary: The study discusses the distribution functions of K mesons, compares them with similar distributions of π mesons, and reveals how their light-front momentum is shared. The research provides the first parameter-free predictions for K distribution functions, emphasizing the need for new experiments sensitive to all K and π DFs.

Summary: In a global QCD analysis, different treatments of valence quark distribution lead to significant differences at large x values, with resummation boosting the total momentum carried by gluons to approximately 40%. The redistribution induced by resummation increases the gluon contribution to the pion mass to approximately 40 MeV.

Summary: In this study, the x-dependent pion gluon distribution from lattice QCD using the pseudo-PDF approach is determined for the first time. The results show that the dependence of the pion gluon parton distribution on lattice spacing and pion mass is mild across different lattice spacings and pion masses. Comparisons with other global fits are also made to validate the findings.

Summary: Quark-antiquark annihilation measurements confirm the asymmetry between down and up antiquarks within protons. The majority of a proton's mass is in the form of quark kinetic and potential energy, as well as gluon energy from the strong force. The presence of more down antiquarks than up antiquarks in protons suggests the need for further study to understand this antimatter asymmetry.

Summary: Accumulating evidence suggests that diquark correlations are important in hadron structure and interactions. Diquark distribution amplitudes are narrower and taller than mesons, influencing momentum distribution. These features could impact baryon distribution functions.

Summary: The new MSHT20 set of parton distribution functions (PDFs) of the proton, determined from global analyses of hard scattering data, includes updates such as improved parameterizations, new precise data, and NNLO QCD corrections. The NNLO fit is strongly favored over the NLO due to wider range and increased precision of data included in the fit, resulting in reduced uncertainties in predictions for processes such as Higgs, top quark pair, and W, Z production at post LHC Run-II energies.

Summary: The emergence of the bulk of the Universe's visible mass and the mechanisms behind the structure of hadrons are profound questions that are being investigated through the study of pseudoscalar mesons like the pion and kaon. Different approaches such as continuum QCD phenomenology, lattice-regularised QCD, and global analysis of parton distributions are being utilized to explore the partonic structure and mass mechanisms of these mesons. Experimental measurements, including those from the anticipated electron-ion collider, will provide valuable insights into the structures of pions and kaons, aiding in a better understanding of their properties and roles in QCD.

Summary: In the standard model of particle physics, there are two mass generating mechanisms: one related to the Higgs boson which is well understood, and the other embedded in quantum chromodynamics responsible for the emergence of hadronic mass, which remains puzzling. Recent progress has been made using theoretical tools like continuum Schwinger function methods and lattice-regularised QCD to understand these mechanisms better and shed light on Nature's Nambu-Goldstone modes. New experimental facilities are expected to contribute greatly in resolving the puzzles of emergent hadronic mass.

Summary: The EicC project in China proposes to construct an Electron-ion collider based on an upgraded heavy-ion accelerator, providing highly polarized electrons and protons with variable center of mass energies. The main goals include precise measurements of nucleon structure, partonic structure of nuclei, interaction with nuclear environment, and exotic states with heavy flavor quark contents. A hermetical detector system with cutting-edge technologies will be constructed to achieve these physics goals.

Summary: Understanding the difference in the scale of emergent hadron mass in proton and pion may require mapping and comparing the distribution functions of all partons within each. The difficulty in predicting the proton's distribution functions lies in it being a three-body bound-state problem, while the pion's two-body problem allows for more accurate predictions. The alignment of theory in this area is promising, especially with experimental facilities now able to test rigorous theory predictions concerning Nambu-Goldstone bosons.

Summary: This study presents a calculation of the pion and kaon Mellin moments extracted directly in lattice QCD using a three-derivative local operator. The results are converted to the MS scheme and evolved at a scale of 2 GeV with three-loop expressions in perturbation theory. Excited states contamination is evaluated to determine the systematic error and additional analyses are performed to reconstruct the x-dependence of the pion and kaon PDFs.

Summary: In this study, results on the quark unpolarized, helicity, and transversity parton distributions functions of the nucleon were presented using the quasiparton distribution approach within the lattice QCD framework. Nonzero results for the disconnected isoscalar and strange quark distributions were found, providing valuable input to the understanding of the nucleon structure.

Summary: Analytic functional forms for parton distribution functions (PDFs) cannot be uniquely determined solely based on discrete experimental measurements due to a mathematical property of mimicry of PDF parametrizations. Instead, predictions of nonperturbative QCD approaches for the x dependence of PDFs should be cast in a form that enables decisive comparisons against experimental measurements. Effective power laws of (1 - x) dependence of PDFs may play a key role in these comparisons.

Summary: In this study, unpolarized and polarized gluon distributions were investigated and parameterized to obtain consistent results, with a focus on their applications to Ioffe-time distributions in lattice QCD calculations. Our results can guide the extrapolation of lattice QCD data and help regulate the ill-posed inverse problem of extracting gluon distributions. Phenomenological approaches are important in obtaining complementary information and discussing higher-twist effects and systematic uncertainties in contemporary first-principle calculations of parton distributions.

Summary: The new parton distribution functions (PDFs) from the CTEQ-TEA collaboration are determined using a wide variety of high-precision Large Hadron Collider (LHC) data, in addition to other datasets. These PDFs are analyzed at next-to-leading order and next-to-next-to-leading order, with error sets determined using the Hessian method. The data sensitivity and preference towards quantities such as α(s)(m(Z)), and the gluon and strange quark distributions are quantified using fast PDF survey techniques.
