Chiral symmetry and open-charm mesons
T. Hilger🇩🇪 · B. Kampfer🇩🇪
Abstract
Pseudo-scalar and scalar mesons are considered within the QCD sum rule approach. We present an analysis of the mass splitting of the pseudo-scalar D - D-bar mesons and the relation to QCD condensates. Weinberg type sum rules are derived for chiral partners which highlight the role of the chiral condensate.
