We present an extension of the Bayesian reweighting procedure to the case of multiple independent extractions of TMDs from SIDIS and $e^+e^-$ data, namely the quark Sivers, transversity and Collins TMD functions. The reweighting is performed using $A_N$ data measured in $p^\uparrow p \to \pi X$ collisions at RHIC. The agreement with $A_N$ data at large-$x_F$ values, a kinematical region...

Deep Inelastic Scattering at large Bjorken $x$ provides an interesting and unique framework to test modern factorization techniques. Although this topic has been widely discussed in the past within the context of effective theories, a consistent treatment in full QCD still faces issues regarding the treatment of rapidity divergences, subtractions, and the role played by soft radiation. In this...

Diffractive processes are events with large rapidity gaps, which typically comprise a double-digit percent of events at colliders and are important for small-$x$ physics. We present a comprehensive factorization of $ep$ diffraction, using effective field theory. We show that there are four nontrivial unpolarized diffractive structure functions at leading power, including the conventional...

Understanding the 3D quark-gluon structure of nucleons is entering an era of precision, which is furthered by the 12 GeV upgrade at Jefferson Lab and the upcoming EIC. I will give an overview of the work done by the EXCLusives via Artificial Intelligence and Machine learning (Exclaim) collaboration, an interdisciplinary effort by ML experts, nuclear theorists and experimentalists centered...

We introduce a string-based parametrization for nucleon quark and gluon generalized parton distributions (GPDs) that effectively handles all skewness values. Our approach leverages conformal moments, representing them as the sum of spin-j nucleon A-form and skewness-dependent spin-j nucleon D-form factor, derived from t-channel string exchange in AdS spaces. This model-independent framework,...

Particular gluon transverse momentum dependent distributions (TMDs and GTMDs) become Wilson loop correlators in the limit of small x. In this talk I will discuss the consequences of this and what happens under evolution.
