Physics Opportunities at ELFE

چکیده
I review some central physics opportunities at the 15 . . . 30 GeV continuous beam electron accelerator ELFE, proposed to be built in conjunction with the DESY linear collider. Our present detailed knowledge of single parton distributions in hadrons and nuclei needs to be supplemented by measurements of compact valence quark configurations, accessible through hard exclusive scattering, and of compact multiparton subsystems which contribute to semi-inclusive processes. Cumulative (x > 1, xF > 1) processes in nuclei measure short-range correlations between partons belonging to different nucleons in the same nucleus. The same configurations may give rise to subthreshold production of light hadrons and charm. Talk given at the meeting on Future Electron Accelerators and Free Electron Lasers, Uppsala, April 25-26, 1996. Work supported in part by the EU/TMR contract ERB FMRX-CT960008.

The theoretical framework of hard exclusive reactions is reviewed with special emphasis on the Elfe project program. Perturbative QCD studies have shown that factorization properties allow to separate well-defined non perturbative objects which are crucial in the understanding of confinement dynamics from perturbatively calculable hard processes. The applicability of this factorization in a def...

A 15-30 GeV continuous beam electron facility has been proposed by nuclear physicists in Europe to study how color forces build up hadrons from quarks and gluons. This project and its physics case are briefly reviewed. The recommendations of NuPECC, the Nuclear Physics Committee of the European Science Foundation are presented.
