Transverse momentum department parton distributions (or simply, TMDs) and generalized parton distributions (GPDs) are fundamental quantum correlation functions of quarks and gluons (collectively referred to as partons) of nucleons and nuclei. They encode rich information that can unravel many aspects of the confined quark and gluon structure of nucleons in momentum and coordinate space,...

Extracting the quark and gluon structure of hadrons from high-energy scattering data is a challenging inverse problem that requires flexible representations, efficient QCD calculations, and reliable uncertainty quantification. I will discuss recent progress toward a computational framework that connects measured events directly to the underlying partonic correlation functions. A central...

In this talk I will discuss azimuthal modulations in lepton and heavy-quark pair production in ultraperipheral collisions (UPCs) of highly charged ions. A full description of the cross section in terms of Generalized Transverse Momentum Dependent parton distributions (GTMDs) for photons is given including a consideration of the Fourier transform to impact parameter space. In particular, this...

The Balitsky-Kovchegov evolution equation, which governs QCD processes at high energy and can account for gluonic saturation effects in this limit, suffers from the presence of large collinear logarithms that make the perturbative expansion unstable. We develop a systematic framework to deal with such logarithms in terms of a scheme transformation within the standard high energy Operator...

In this talk, I will present the skewness dependence of the pion and kaon generalized parton distributions at different momentum transfers within the covariant Nambu-Jona-Lasinio model, employing the Schwinger proper-time regularization scheme to regulate ultraviolet divergences and implement an effective description of quark confinement. Our prediction results for the pion and kaon GPDs and...

Generalized transverse-momentum-dependent distributions (GTMDs) provide a phase-space description of partons and a natural framework for studying orbital angular momentum in the nucleon. In particular, the canonical quark orbital angular momentum (OAM) density is encoded in a transverse-momentum moment of the GTMD $F_{14}$. Beyond tree level, however, this moment is ultraviolet divergent, and...

The Color Glass Condensate (CGC) is the effective theory for dense gluonic matter in the small-x regime of QCD, with forward-rapidity particle production in p+A collisions offering a sensitive testing ground. In this presentation, we introduce MC-CGC v3.0, a CGC-based Monte Carlo model upgraded to handle heavy-ion systems. This numerical approach extends previous analytic studies by...

Gravitational form factors are related to a particular moment of the GPDs, and are relevant to EIC physics. Gravitational form factors are defined as the hadron matrix elements of the energy-momentum tensor (EMT). In QCD, the gauge-invariant part of the EMT is expressed as a sum of the several composite operators built from quark and gluon fields. Although the total EMT is finite and is not...

A framework is presented in which the baryon decouplets treated as a resonance in QCD sum rules and its decay width is determined self-consistently. The δ-pole approximation of the two-point correlation function is analytically continued to a complex-

I would present recent developments in theoretical calculations of Sivers asymmetry in almost back-to -back photo and electroproduction of J/psi and jet/photon production in the kinematics of EIC. J/psi production is treated in NRQCD. I'll show that this provides an excellent tool to probe the gluon Sivers function. I'll discuss the effect of TMD evolution and scheme dependence on the cross...
