Chiral-partner D mesons in a heat bath within QCD sum rules
Thomas Buchheim, Thomas Hilger, Burkhard Kampfer +1
Utilizing QCD sum rules, we extract the temperature dependences of the spectral properties of the pseudo-scalar and scalar D mesons regarded as chiral partners. Besides the masses…

Algebraic vacuum limits of QCD condensates from in-medium projections of Lorentz tensors
Thomas Buchheim, Burkhard Kampfer, Thomas Hilger
Utilizing the in-medium Lorentz decomposition of operators generating QCD condensates we derive general constraints among the latter ones by the requirement of a smooth transition…

Chiral symmetry aspects in the open charm sector
Thomas Buchheim, Thomas Hilger, Burkhard Kampfer
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 med…
