1 PublikationChiral QCD sum rules for open-charm mesons
Hilger, T.; Kämpfer, B.; Leupold, S.
Abstract
QCD sum rules for chiral partners in the open-charm meson sector are presented at nonzero baryon net density or temperature. We focus on the differences between pseudo-scalar and scalar as well as vector and axial-vector D mesons and derive the corresponding Weinberg-type sum rules. This allows for the identification of such QCD condensates which drive the nondegeneracy of chiral partners in the lowest order of the strong coupling αs and which, therefore, may serve as “order parameters” for chiral restoration (or elements thereof).
