Role of Four-Quark Condensates in QCD Sum Rules
R. Thomas🇩🇪 · T. Hilger🇩🇪 · B. Kampfer🇩🇪
Abstract
The QCD sum rule approach to the in-medium behavior of hadrons is discussed for omega meson, nucleon and D meson. Emphasis is devoted to the impact of four-quark condensates and to order parameters of spontaneous symmetry breaking.
