Role of Four-Quark Condensates in QCD Sum Rules
arXiv:0711.2956 · doi:10.1016/j.ppnp.2007.12.028
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.
