The latter enables the evaluation of the orbital angular momentum contribution to the nucleon spin through Ji’s sum rule, and helps us...

Hadrons are composite particles composed of quarks bound by the strong interaction and are conventionally classified into baryons ($qqq$), consisting of three quarks, and mesons ($q\bar{q}$), consisting of a quark-antiquark pair.

Exclusive meson electroproduction experiments allow for the study of baryon structure. Investigating nucleons at this scale probes the fundamental structure of the universe.

Meson-baryon scattering amplitudes exhibit a rich phenomenology, including exotic states, coupled-channel effects, and flavor-driven dynamics.

The strongest force in nature binds quarks and gluons into hadrons, confining them under ordinary conditions. Collisions of heavy nuclei at the Relativistic Heavy Ion Collider (RHIC) just ended in 2026 after 25 years of running.

Hyperons play a central role in the composition of dense baryonic matter and are expected to emerge in the cores of neutron stars at supra-nuclear densities, influencing the equation of state.

Available partial-wave data in the Roper and the isobar sub-channels are described,...

The structure of the lightest scalar meson remains one of the puzzles in particle and hadron physics. The breaking of scale symmetry in QCD provides a source of the scalar field, dilaton, and establishes the foundation of chiral-scale effective field theory (EFT) where the chiral symmetry is nonlinearly realized but an iso-scalar scalar field is included. The chiral-scale EFT has been...

Hyperon-Nucleon interactions are expected to play an important role in the dynamics of Neutron Stars, as well as the quark-hadron transition and cooling which occurred in the early universe. In particular the so-called ‘Hyperon Puzzle’, wherein accounting for Hyperons in neutron star equations of state leads to a disagreement with astronomical observations, shows a need for a better...

Abstract: I will review what my collaboration groups found on N with hidden strangeness in γp → KΛ, γp → KΣ, γp → KΣ, γp → KΣ, and their open strange partners in KLp→π+Σ0, K−p → KΞ reactions inn last two years. More production processes of the penta-quark states with strangeness are proposed to further test the hadronic molecular picture.

In this talk, we discuss the recent progress in lattice QCD determinations of generalized parton distributions. The recently developed framework of asymmetric frames of reference, now complete for the vector, axial vector and tensor cases, allows for cost effective calculations of GPDs across a broad range of kinematics. This makes the prospects of their full mapping realistic in the near...

In this talk I will review the phenomena of dynamically generated resonances that lead to two-pole structures in the meson-baryon interaction, as the $\Lambda(1405)$ or in the heavy meson-light meson interaction, as the $D_0^*(2300)$. Studying the quark mass dependence of these states can help significantly to classify exotic states according to the SU(3) symmetry. LQCD simulations on these...

In recent years, there was significant progress in the experimental study of the electromagnetic structure of baryons in the timelike region through electron-positron scattering reactions with the creation of baryon-antibaryon pairs: $e^+ e^- \to B \bar B^\prime$. From the annihilation cross sections, we can determine the electromagnetic form factors of baryons in terms of the square transfer...

We study the analytic structure of the non-perturbative quark propagator. To this end, we solve the coupled Schwinger-Dyson equations of the quark propagator and the quark-gluon vertex over a region of the complex plane. Retaining the full tensor structure of the quark-gluon vertex, we find that, in the sub-GeV time-like momentum region, the associated quark propagator exhibits real poles with...

Quark--hadron duality --- the averaging of resonance-region structure functions to perturbative QCD scaling behavior --- links the hadronic and partonic pictures of the nucleon.

Today, many nucleon resonances are known and more are being discovered. They are the most fundamental three-body systems in Nature. Working with a Poincare-covariant quark+diquark, q(qq), Faddeev equation approach to nucleon and its resonance structure, a refined symmetry preserving current is developed. The parameters in the interaction current are chosen to ensure that the q(qq) picture...

Nucleon gravitational form factors are defined through the nucleon matrix element of the energy-momentum tensor and characterize the energy, pressure, and shear forces inside the nucleon. In particular, the gravitational form factor $D(t)$, which is associated with the spatial components of the energy-momentum tensor matrix element, plays an important role in describing the internal stress...

The $\Lambda(1670)$ plays an important role in the chiral dynamics of meson-baryon interaction. In the chiral unitary approach, it is dynamically generated from the interaction of the SU(3) octets of pseudoscalar mesons and baryons. The $\Lambda(1670)$ is related to the $\Lambda(1405)$, as both resonances originate from the same coupled-channel meson-baryon dynamics. However, the nature of the...

The $\Lambda\eta$ threshold region is of particular interest for understanding the excitation spectrum of $\Lambda$ hyperons. Previous measurements of the $K^-p\to\Lambda\eta$ reaction revealed a strongly non-uniform angular distribution near threshold. Since a $J^P=1/2^-$ resonance is expected to produce a nearly isotropic angular distribution in this region, the observed behavior cannot be...

Within the framework of the Hypercentral Constituent Quark Model (HCQM), we investigate the spin-dependent mass spectra of all-heavy pentaquark configurations, treating them as effective three-body systems composed of two correlated diquarks and an antiquark.

Investigating the structures of baryon resonances is one of the fundamental tasks in hadron physics.
