<div style="direction: ltr;">Dear Colleagues,</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">We are pleased to announce the 2025 summer school <b>
"Quantum Chromodynamics and muldimensionnal hadron structure”</b> (<a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__indico.in2p3.fr_event_33198_overview&d=DwMGaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=Gx3WKoMVriglYsTSKLV7HQ&m=lMUCp5Bza_VxZsL59dRC8cWt_7OCvHiBGx8l6AIWBB4MZBu2ERKDfqZs0FGryKA6&s=Iy0nIrds6jYcvVCKLhVnIyqiOjQGx1rOSD6weKdAqrM&e=" id="OWAbf6f685a-59f0-d6c2-3c09-7d0c3d7c9b19" class="OWAAutoLink" data-auth="NotApplicable">https://indico.in2p3.fr/event/33198/overview</a>)
that will take place <b>from July 7th to July 11th at the IJCLab in Orsay</b>, close to the city of
<b>Paris (France)</b>. The school welcomes all PhD students and young postdocs in the fields of QCD, hadron and/or heavy-ion physics, both experimentalists and theorists.</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">The experiments at JLab, COMPASS, RHIC, the LHC in ultra-peripheral collisions, and the future EIC offer the prospect of accessing the multidimensional quark and gluon (parton) content of hadrons with great precision in the near
future, across a very wide range of energies. The parton distributions that describe this content include PDFs (longitudinal momentum distributions), GPDs (related to transverse position distributions), TMDs (transverse momentum distributions), and GTMDs (which
unify the previous distributions). In the regime of very high energies, the partonic content of hadrons is dominated by their gluonic content, which involves collective effects of the saturation type. The purpose of this school, aimed at both theorists and
experimentalists, is to present these different distributions, their interrelations, the associated phenomenology, as well as the current and upcoming experimental results and programs that enable access to these distributions.</div>
<div style="direction: ltr;"><br>
</div>
<div style="direction: ltr;">The essence of this series of schools (held in 2012, 2014, 2016, 2018, 2023, and 2024) includes:</div>
