With the project to build a future Electron-Ion Collider (EIC) at BNL, equipped with a new state-of-the-art detector (ePIC), and advancements in theory and further development of phenomenological tools, we are now preparing for the next step in subnuclear tomographic imaging. The EIC's large range of center-of-mass energies in combination with high luminosity and polarization of both the...

Solenoidal Large Intensity Detector (SoLID) is a large acceptance, high luminosity device proposed for exploiting the full potential of the Jefferson Lab (JLab) 12 GeV energy upgrade. The scientific program of SoLID includes six approved experiments: three Semi-Inclusive Deep Inelastic Scattering (SIDIS), two Parity-Violating Deep Inelastic Scattering (PVDIS), and one $J/\psi$ production. As a...

Precise measurement of Generalized Parton Distribution function (GPDs) is a key task to understand the 3-dimensional nucleon structure. There have been attempts to measure GPDs via lepton induced deep inelastic scattering (DIS) reactions. On the other hand, measurements with hadron induced reactions have not been carried out yet. Hadron induced reactions are complementary to the DIS reactions....

In previous works, the two-nucleon potential has been successfully determined to a high-precision level in the framework of chiral effective field theory. Nonetheless, there are still some free parameters of this potential, which cannot be extracted from two-nucleon data. The goal of the work presented in this talk is to adjust these parameters using three-nucleon data. Because of the high...

In this talk we present the latest results about the extraction of Transverse-Momentum-Dependent (TMD) distributions. We discuss the extraction of unpolarized quark TMD Parton Distribution Functions (TMD PDFs) in the proton and in the pion, as well as TMD Fragmentation Functions (TMD FFs), from global fits of Drell-Yan and Semi-Inclusive Deep-Inelastic Scattering (SIDIS) data sets made by the...

The dynamics of the three-nucleon system can be very extensively tested by means of the deuteron-proton breakup reaction. Experimental studies of the dp system expose various dynamical ingredients, like three-nucleon force (3NF) and Coulomb force, which play an important role in correct description of observables (e.g. cross section). The cross sections as well as polarized observables (e.g....

In order to investigate Few-Particle Hypernuclei within the framework of the Hyperspherical Function Method, it is necessary to obtain full wave functions that are anti-symmetric under particle interchange. These wave functions must include not only hyperspherical, but also spin-isospin parts. According to the Parentage Scheme of Symmetrization, N-particle hyperspherical functions (N=3,4,5,6…)...

The issue of a proper definition of the spatial distributions of matrix elements of local operators has attracted much attention in the last few years. In the talk, the novel definition of electromagnetic and gravitational local spatial densities of hadrons will be discussed. We will start from the matrix elements parametrised in terms of the form factors and connect them with the...

Hard Exclusive Meson Production (HEMP) and Deeply Virtual Compton Scattering (DVCS) are very promising reactions to access Generalized Parton Distributions (GPDs). Such exclusive measurements were performed at COMPASS in 2016 and 2017 at the M2 beamline of the CERN SPS using the 160 GeV muon beam scattering off a 2.5 m long liquid hydrogen target surrounded by a barrel-shaped time-of-flight...

Generalized Parton Distributions (GPDs) are a well-established tool for exploring the 3D structure of the nucleon and mechanical properties such as the distributions of energy/momentum and forces in the system. While extensive studies have been performed for the ground-state nucleon, little is known about the 3D structure of resonances. The nucleon-to-resonance (N->N*) transition GPDs provides...

In this talk, I will present our recent result on the leading one-loop corrections to the gravitational form factors of the delta resonance in the framework of chiral effective field theory. Various contributions to the energy–momentum tensor and the renormalization of the low-energy constants are worked out.

GPD phenomenology experiences an acceleration with a lot of recent results: exploration of new exclusive processes with enhanced sensitivity to GPDs, more sophisticated treatments of experimental uncertainty, kinematic and higher-twist corrections, and the first results from lattice QCD with non-local matrix elements. I will outline the challenges posed by GPD extraction and strategies to make...
