Studies of the spectrum of hadrons and their structure both for the ground and excited states in experiments with electromagnetic probes offer unique insight into many facets of the strong interaction in the regime of large quark-gluon coupling that underlies the hadron generation. The successful start of the new 12-GeV era of experiments in the four halls at Jefferson Lab in the U.S., as well as the experiments at the European facilities ELSA, MAMI, and GSI, and the Asian facilities BES, SPring-8, and JPARC, have considerably extended the scope of research in hadron physics. For the first time, these experiments make possible: (a) the mapping of the 1-D and 3-D momentum and spatial distributions of partons within mesons and baryons and the accessing of the components of the hadron energy-momentum tensor in terms of mass, spin, and pressure distributions, (b) exploring the dynamics and impact of hadron mass generation with nucleon elastic, N->N* transitions, and meson elastic/transition form factors and parton distribution amplitudes, and (c) searching for new states of hadronic matter including the so-called hybrid mesons and baryons. Impressive progress in relating the hadron structure observables to the strong QCD mechanisms was achieved from the ab initio QCD description of hadron structure to a diverse array of methods in order to expose emergent phenomena via quasi-particle formation.

Reimei Symposium on
“Synergies in Hadron Physics between J-PARC and JLab”
This symposium is part of the Reimei series of workshops. Reimei means “dawn” in Japanese, and the symposium will highlight the physics being done now, or in the near future, at J-PARC which has overlap with the hadronic physics program at Jefferson Lab. The opportunities to discover new phenomena in hadronic physics, such as new (and possibly hybrid) baryon resonances, is enhanced when data from both hadronic beams and electromagnetic beams are used to constrain the partial wave analysis (PWA) of common final-state reaction products. This symposium will provide discussion that can lead to a new dawning of research collaboration between J-PARC and JLab.
