Chiral symmetry and open-charm mesons

Nuclear Theory 2010-02-18 v1

Abstract

Pseudo-scalar and scalar DD 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.
