Precocious Scaling in Antiproton - Proton Scattering at Low Energies [PDF]

open access: yesarXiv, 1993
The scaling of the diffraction peak in antiproton--proton scattering has been investigated from near threshold up to $3\,\,\, GeV/c$ laboratory momenta.It was shown that the scaling of the differential cross sections are evidentiated with a surprising accuracy not only at high energies,but also at very low ones(e.q.

ELFE Physics [PDF]

open access: yesarXiv, 1999
This is an introductory review of central topics in hadron physics that are addressed by high intensity, continuous electron beam facilities in the multi-GeV range. Exclusive processes are a crucial tool for increasing our knowledge of hadron wave functions beyond what can be learned from studies of hard inclusive processes.
