Chiral symmetry aspects in the open charm sector


Chiral symmetry aspects in the open charm sector

Buchheim, T.; Hilger, T.; Kämpfer, B.

QCD sum rules serve as tools to investigate changing hadronic properties in a hot and/or dense nuclear medium. The role of chiral symmetry breaking and restoration effects in a medium can be addressed also in the heavy-light meson sector. Thus, we consider Weinberg sum rules which refer to chiral partner mesons composed of a light and a heavy quark.
