Tentative Agenda

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.

This Workshop aims to develop plans and to facilitate the future synergistic efforts between experimentalists, phenomenologists, and theorists working on studies of hadron spectroscopy and structure with a goal to elucidate hadron emergence from QCD. The Workshop topics include:

  • Determination of hadron 3-D imaging and the mass, momentum and pressure distributions within hadrons from the data of experiments with electromagnetic probes;
  • Insight into 1-D meson and baryon parton distributions;
  • Meson and baryon spectroscopy and the search for new states of hadronic matter in photo- and electroproduction experiments;
  • Studies of hadron elastic/transition electromagnetic form factors;
  • Advances and prospects of ab initio QCD descriptions of the hadron spectrum and elastic/transition electromagnetic form factors;
  • Emergence of hadron structure within continuum QCD approaches and their impact on experiments with electromagnetic probes;
  • Quark model advances in the description of the hadron spectrum and the elastic and transition electromagnetic form factors;
  • Development of a QCD-rooted theory framework for the unified description of hadron structure from 1-D form factors, PDFs, and PDAs to 3-D femto-images;
  • Relating the nucleon and meson structure to atomic nuclear structure;
  • Studies of the impact of these efforts on the science case for a future Electron-Ion Collider.

 

Pre-workshop Reimei Symposium agenda

November 5, 2019

The pre-workshop Reimei Symposium is titled “Synergies in Hadron Physics between J-PARC and JLab”, with the goal of enhancing the connections of research interests being done in the area of hadron physics around the world, and in particular between J-PARC in Japan and Jefferson Lab in the USA.
