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…
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…
Observing the Odderon: Tensor Meson Photoproduction
E. R. Berger, A. Donnachie, H. G. Dosch +1
We calculate high-energy photoproduction of the tensor meson by odderon and photon exchange in the reaction , where X is either th…
Soft High Energy Scattering in Nonperturbative QCD
E. R. Berger
In this report diffractive high energy reactions are discussed in a functional integral approach where hadronic amplitudes are calculated from vacuum expectation values of lightlik…
Odderon and photon exchange in pseudoscalar meson production
E. R. Berger
We consider exclusive production in ep-scattering. At high energies odderon and photon exchange contribute. The photon exchange contribution is evaluated exactly using data f…
