Probing generalized parton distributions in pi N -> l+ l- N
E. R. Berger, M. Diehl, B. Pire
We study the exclusive reactions pi- p -> l+ l- n and pi+ n -> l+ l- p$ in view of possible future experiments with high-intensity pion beams. For large invariant mass of the lepto…
Timelike Compton scattering: exclusive photoproduction of lepton pairs
E. R. Berger, M. Diehl, B. Pire
We investigate the exclusive photoproduction of a heavy timelike photon which decays into a lepton pair, gamma p -> l+ l- p. This can be seen as the analog of deeply virtual Compto…
Femto-Photography of Protons to Nuclei with Deeply Virtual Compton Scattering
John P. Ralston, Bernard Pire
Developments in deeply virtual Compton scattering allow the direct measurements of scattering amplitudes for exchange of a highly virtual photon with fine spatial resolution. Real-…
Generalized parton distributions in the deuteron
E. R. Berger, F. Cano, M. Diehl +1
We introduce generalized quark and gluon distributions in the deuteron, which can be measured in exclusive processes like deeply virtual Compton scattering and meson electroproduct…
