Analysis of heavy mesons in nuclear matter with a QCD sum rule approach

Abstract

In this article, I calculate the contributions of the nuclear matter induced condensates up to dimension 5, take into account the next-to-leading order contributions of the nuclear matter induced quark condensate, study the properties of the scalar, pseudoscalar, vector and axial-vector heavy mesons in the nuclear matter with the QCD sum rules in a systematic way, and obtain the shifts of the masses and decay constants. Furthermore, I study the heavy-meson-nucleon scattering lengths as a byproduct, and obtain the conclusion qualitatively about the possible existence of heavy-meson-nucleon bound states.
