The EMMI Rapid Reaction Task Force (RRTF) workshop, titled
“Impact of Vector Mesons on the Studies of the 3D Structure of the Nucleon,”
will be held at CERN from 15 to 18 June 2026.

In accordance with the RRTF framework, this strategic working meeting is designed to bring together a focused group of world-leading experts to address a specific scientific challenge: the significant and often complicating role of diffractive vector mesons (VMs) in the interpretation of 3D nucleon structure data. While hadron production in Deep Inelastic Scattering (DIS) is a primary tool for mapping quark-gluon
