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…
Wilson coefficients and four-quark condensates in QCD sum rules for medium modifications of mesons
Thomas Buchheim, Thomas Hilger, Burkhard Kampfer
Wilson coefficients of light four-quark condensates in QCD sum rules are evaluated for pseudo-scalar mesons, thus, pushing the sum rules toward mass dimension six. Contrary to…
Heavy-quark expansion for D and B mesons in nuclear matter
Thomas Buchheim, Thomas Hilger, Burkhard Kampfer
The planned experiments at FAIR enable the study of medium modifications of and mesons in (dense) nuclear matter. Evaluating QCD sum rules as a theoretical prerequisite for…
Defining medium-specific condensates in QCD sum rules for and mesons
T. Buchheim, T. Hilger, B. Kampfer
QCD sum rules for and mesons in a strongly interacting environment require the decomposition of Gibbs averaged operators related to tensor structures. We present a procedur…
In-medium QCD sum rules for D mesons: A projection method for higher order contributions
Thomas Buchheim, Thomas Hilger, Burkhard Kampfer
D mesons serve as excellent probes of hot and/or dense strongly interacting matter. They can provide insight into the restoration of chiral symmetry. The chiral condensate as well…
Four-quark condensates in open-charm chiral QCD sum rules
Thomas Hilger, Thomas Buchheim, Burkhard Kampfer +1
Recently, in Hilger et al. (2011) [1] QCD sum rules for chiral partners in the open-charm meson sector have been presented at nonzero baryon net density or temperature up to and in…
