National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Chiral Restoration in the Nuclear Medium.

DE2007921053

Publication Date	2007
Page Count	8
Abstract	The theory of the strong interaction, Quantum Chromodynamics (QCD), has been extremely successful in describing high-energy and short-distance-scale experiments involving quarks and gluons. Applying QCD to low energy and large-distance-scale experiments has however been a major challenge. Although the rapidly increasing strength of the interaction in this latter case makes it impossible to apply perturbative techniques, the symmetries of QCD (such as chiral symmetry) provide guiding principles to deal with strong interaction phenomena. Various QCD-inspired predictions are now available in the non-perturbative domain, which can be tested experimentally at current hadron and electromagnetic facilities.
