Quark condensate in nuclear matter based on nuclear Schwinger-Dyson formalism
- Department of Physics, Saga University, Saga 840 (Japan)
The effects of higher order corrections of ring diagrams for the quark condensate are studied by using the bare vertex nuclear Schwinger-Dyson formalism based on {sigma}-{omega} model. The correction of the ring diagrams affects the quark condensate when the {sigma} meson {open_quotes}{sigma} term{close_quotes} is large. {copyright} {ital 1997} {ital The American Physical Society}
