  The recent exclusive backward-angle electroproduction of omega from Jefferson
Lab Hall C electron-proton fixed-target scattering experiments above the
resonance region hints at a new domain of applicability of QCD factorization in
a unique u-channel kinematics regime. Thanks to this effort, the interest in
studying nucleon structure through u-channel meson production observables has
grown significantly. In the fixed target configuration, the u-channel meson
electroproduction observables feature a unique interaction picture: the target
proton absorbs nearly all momentum induced by virtual photons and recoils
forward, while the produced mesons (such as omega or pions) are left behind
almost at rest near the target station. In this presentation, We provide a
summary of the key observations of the existing u-channel meson production
results, update-to-date theory insights, and a path to further exploration from
JLab 12 GeV Hall C program to the future Electron-Ion Colliders.
