Abstract: In the past decade, the most important development in nuclear physics has been the establishment of a data-inspired theoretical (GPD) framework that offers the complete spacial and momentum information of quark-gluon constituents within the nucleon. Recent pioneering studies at Jefferson Lab have shown evidence on the extra degrees of freedom of proton wave function that is only accessible through the backward-angle meson production observables and these cannot be described by the current GPD framework. In this colloquium, a brief overview of the theoretical and experimental efforts on studying this unseen proton structure will be given; a later section will introduce a systematic program and the plan on further exploring backward-angle meson production from Jefferson Lab to the future Electron-Ion Colliders.

Speaker: Dr. Wenliang (Bill) Li, Center for Frontiers in Nuclear Science, Stony Brook University
