Four-Quark Condensates in Nucleon QCD Sum Rules
Four-Quark Condensates in Nucleon QCD Sum Rules
Thomas, R.; Hilger, T.; Kämpfer, B.
The in-medium behaviour of the nucleon spectral density including self-energies is revisited within the framework of QCD sum rules. Special emphasis is given to the density dependence of four-quark condensates. A complete catalog of four-quark condensates is presented and relations among them are derived. Generic differences of such four-quark condensates occuring in QCD sum rules for light baryons and light vector mesons are discussed.
