Electromagnetic processes are essential and versatile tools in studying myriad aspects of hadronic and nuclear physics. This talk will offer a tour of the various ways in which electromagnetic processes and probes are used to inform our understanding of hadron structure, hadronization mechanisms, what partonic bound states exist, and properties of extreme nuclear matter. We’ll also consider...
I’ll give my personal perspective on a general overview of the most recent and relevant theoretical developments about how we picture the internal structure of hadrons.
The anomalous magnetic moments of the muon and the electron, 𝑎μ and 𝑎ₑ, are precision benchmarks of the Standard Model and promising New-Physics probes. The hadronic vacuum polarization (HVP) contribution remains the dominant source of uncertainty, a problem compounded by the current tension between data-driven (dispersive) and lattice QCD evaluations. I will discuss the status of the HVP...
The anomalous magnetic moment of the muon, $a_\mu$, remains a benchmark precision test of the Standard Model. The long-standing tension between experiment and theory has driven major progress in recent years, culminating in the latest White Paper, which incorporates state-of-the-art lattice QCD determinations of the hadronic vacuum polarization (HVP). These first-principles results, obtained...
In recent years, a number of charmonium-like XYZ states have been observed above the open-charm threshold in experiments like BABAR, BESIII, Belle(II) and LHCb. Their properties often go against our expectations for regular charmonium states, rendering their interpretation difficult. In this talk, I will give an overview of recent activities aiming to shed light on the nature of the XYZ states.
I will review recent advances in studying three-particle interactions directly from lattice QCD. By employing mathematical relations that connect discrete finite-volume energies and matrix elements to physical scattering and decay amplitudes, it is now possible to calculate observables that go beyond the single-hadron or elastic two-hadron regime. In addition to outlining the formalism, I will...
The detailed understanding of how quantum chromodynamics (QCD) gives rise to the spectrum of hadrons is currently one of the biggest open questions in hadron physics. Most of the observed states are classified as quark-antiquark mesons or three-quark baryons. However, QCD allows for a much richer spectrum with more complex configurations. Experimental evidence exists for such non-conventional...
The PRad-II and X17 Experiments are planned to run in Jefferson Lab’s Hall B in 2026. The common experimental setup includes a large-volume vacuum system, two planes of GEM tracking detectors for improved vertex and angle reconstruction, and a high-resolution calorimeter (HyCal). These experiments strive to give definite answers to long-standing questions in hadron physics. The X17 experiment...
Understanding the interactions among strange hadrons is crucial for developing a realistic equation of state of nuclear matter in dense environments as in the interior of neutron stars. In recent years, significant theoretical progress has been achieved through Effective Field Theories, which provide interaction models anchored to experimental data, and through Lattice QCD calculations that...
The Electron Ion Collider (EIC) is designed to further our understanding of hadronic physics. However, it could also provide opportunities to look for new phenomena beyond the Standard Model. In this talk, we will provide examples of such physics, with a focus on new light particles that may be associated with a dark sector. We will illustrate how the EIC can probe new model parameter space...
I will discuss a lattice QCD calculation of the nucleon electric polarizabilities at the physical pion mass. Our findings reveal the substantial contributions of the Nπ states to these polarizabilities. Without considering these contributions, the lattice results fall significantly below the experimental values, consistent with previous lattice studies. This observation has motivated us to...
An overview of the experimental activities for the study of generalised parton distributions will be presented. These include existing measurements of exclusive processes in lepton-hadron and hadron-hadron interactions as well as planned activities for the future.
Generalized parton distributions (GPDs) offer a powerful framework to access the multidimensional structure of hadrons, allowing in particular for so-called nucleon tomography and providing access to elements of the hadron energy–momentum tensor. The extraction of GPDs from experimental data is, however, challenging and often cannot be performed in a complete way due to difficulties arising...
The never ending story of baryon time-like form factors continues and renew itself, fed by the powerful process of synergic and mutually reinforcing actions of experiments and theory.
Hyperons, with their self analyzing weak decays give the unique possibility to investigate the complex nature of form factors and mainly to test concepts based on first principles, which can be exploited to...
In this talk I will review the current status of transverse momentum dependent (TMD) physics and related phenomena, including both unpolarized and polarized observables. Such studies give us insight into the 3-dimensional structure of hadrons. The focus of the talk will be on recent developments in theory and phenomenology regarding the extraction of TMD parton distribution functions and...
In recent years, significant progress has been made in extracting transverse-momentum-dependent (TMD) hadron structure from lattice QCD. In this talk, I will give a brief overview of recent developments in lattice calculations of TMD physics, including the determination of the soft function, the Collins–Soper kernel, and the computation of TMD parton distribution functions and TMD wave functions.
The existence of two-nucleon short-range correlations (2N SRCs) has been well established by a series of experiments at SLAC and Jefferson Lab. The inclusive measurements showed a universal behavior in A/D cross section ratios of quasielastic scattering at x>1 and moderate Q2 yielding a constant value. In these kinematics mean field contributions fall off rapidly and 2N SRC contributions...
The low-energy limit of QCD is represented by a tower of effective field theories (EFTs): Chiral, Pionless, Halo/Cluster, and Roto-Vibrational, with perhaps others still to be developed. EFTs have transformed the landscape of nuclear theory by providing a systematic framework to account for multi-body forces and currents following the same tenets used in other areas of physics. However, issues...
Lattice QCD has matured into a powerful nonperturbative tool for directly probing the low-energy regime of the strong interaction from the QCD Lagrangian. Specifically, lattice QCD now offers quantitative insights into two- and three-nucleon interactions, nuclear binding energies, hypernuclear forces, and electroweak matrix elements relevant to neutrino-nucleus scattering and double beta...
AMBER is a new QCD facility at CERN's SPS M2 secondary beam line, which aims to study fundamental properties of hadrons. The first approved experimental phase includes measuring the antiproton production cross-section, which is essential for indirect dark matter searches using cosmic-ray antiprotons. It also includes measuring the proton's charge radius using high-energy muons and...
The intensity frontier offers a complementary approach to high-energy colliders, as high-precision measurements can provide unprecedented constraints on new physics, fundamental interactions, and the structure of matter. The Mainz Energy-recovering Superconducting Accelerator (MESA) is a cutting-edge facility that will push the limits of high-intensity, low-energy hadronic physics. MESA’s...
I review recent developments in the field of heavy ion collisions and quark gluon plasma physics with focus on the role of nucleon and nuclear structure, electromagnetic probes, as well as connections to the future Electron Ion Collider.
The status and plans for experimental programs in hadronic physics in Asia, Europe and N. America will be summarized.
The never ending story of baryon time-like form factors continues and renew itself, fed by the powerful process of synergic and mutually reinforcing actions of experiments and theory.

The Electron-Ion Collider will explore the internal structure of nucleons and nuclei with unprecedented precision. By colliding polarized electrons with polarized protons and a range of nuclei across a broad kinematic regime, the EIC will enable multi-dimensional probes of nucleon structure, including TMDs, GPDs, and other partonic correlations. These measurements are essential for...
