 Abstract

The study of electromagnetic transitions opens a window into the very nature of the strong interaction. And, indeed, such a study of how a ground-state nucleon transitions to an excited state, over a broad range of q2, will provide keen insight into the evolution of how dynamically-generated masses emerge from the asymptotically-free, nearly massless quarks of perturbative QCD as well as provide information on the ancillary effects from the meson-baryon cloud. The space-like (q2<0) region has been explored more intensively, particularly at JLab, but efforts have also begun in studying the time-like (q2>0) region at GSI. We are living in exciting times whereby near-future prospects exist in extracting high-quality data in both the space-like and time-like regimes (JLab12 and FAIR, for example). Holding the proposed meeting will bring together several disparate experimental and theoretical communities and thereby help in making the very first steps towards a much needed consistent description spanning these two kinematical regimes in q2. The discussions will further include photoproduction measurements (ELSA, JLab, LEPS, and MAMI), wherein the q2=0 point anchors the connection between space-like and time-like regions and meson-beam data (GSI, FAIR, and J-PARC) and amply complements the requisite information for baryon spectroscopy. Finally, studies of in-medium vector meson spectral function modifications, which are related to the electromagnetic transitions in the time-like region will also be addressed.

ECT* - European Centre for Theoretical Studies in Nuclear Physics and Related Areas

                  

The European Centre for Theoretical Studies in Nuclear Physics and Related Areas (ECT*) in Trento (Italy) provides a dedicated and structured combination of scientific activities for a large international scientific community. ECT* acts as an "intellectual" centre of competence, complementary in scope and activities to existing research facilities based at universities or experimental laboratories. It promotes coordination of European research efforts in nuclear physics and related research areas.
