The interplay of hadron properties and their modification in an
ambient nuclear medium on the one hand and spontaneous chiral
symmetry breaking and its restoration on the other hand is
investigated. QCD sum rules for various heavy-light pseudoscalar
mesons embedded in cold nuclear matter are evaluated, the impact of
order parameters is investigated and Weinberg type sum rules are
derived. The consequences of a chirally symmetric scenario for the
rho meson are investigated and the complementarity of mass shift
and broadening is discussed. Additionally, the analytic structure
of quark propagators in the complex plane is investigated
numerically within Dyson-Schwinger equations. The applicability of
Bethe-Salpter equations for heavy-light quark-antiquark bound
states in the scalar and pseudo-scalar channels by variation of the
momentum partitioning parameter is presented. The solutions of the
Dyson-Schwinger equation in the Wigner-Weyl phase are used to
investigate the hadron spectrum with explicit but without dynamical
chiral symmetry breaking. An exhaustive introduction to chiral
transformations within classical and quantum field theory and
current-current correlators is given.
