3DPartons week
3DPartons is a virtual access infrastructure supported by the European project STRONG-2020. 3DPartons gives access to open-source computing codes necessary for high precision phenomenology in the field of 3D hadron structure. Benefiting from the experience of decades of parton distribution function (PDF) studies, the GPD and TMD communities can find in 3DPartons a forum where they can mutualize knowledge and know-how about scientific and technical problems related to the complexity of the GPD and TMD computing chains.

EpIC: A Monte Carlo event generator for exclusive processes 30m
There has been an increasing interest in exclusive processes in recent years. Part of this interest stems from the open questions of how the spin of the proton is decomposed into its intrinsic spin and orbital motions, along with the possibility of gaining energy-momentum densities through exclusive processes. During this presentation, we will introduce the EpIC Monte Carlo event generator. By utilizing the PARTONS framework, the EpIC generator offers a flexible structure and a variety of model options which make it an attractive tool for the community. In addition, the EpIC generator incorporates first-order radiative corrections in its architecture. Therefore, EpIC offers a comprehensive set of features that will enable nucleon structure to be studied more deeply through impact studies on future electron-ion colliders.

Aspects of the modelling of GPDs at very small Bjorken-x 30m
Heavy meson photoproduction in UPC provides a welcome indirect access to gluon PDFs in the very small x region. Technically, the cross-section involves generalised parton distributions (GPDs). A popular proposal to relate the GPDs to PDFs based on the Shuvaev transform has been used to interpret recent experimental data. I propose to discuss in detail the regime of validity of this proposal and to provide tools to quantify the level of uncertainty one can expect from such modelling.
