Quark mass dependence of hadronic observables

F.-K. Guo (ITP)  / U.-G. Meißner (UB) / P.Wang (IHEP)


The study of the quark mass dependence of the properties of heavy-light systems done in the first funding period will be extended to more general hadronic observables. Furthermore the investigations on disconnected Wick contraction contributions to hadronic observables done in leading order will now be extended to next-to-leading order in chiral perturbation theory for various quark masses.
