Abstract

In this article, I calculate the contributions of 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 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 conclude qualitatively about the possible existence of heavy-meson–nucleon bound states.
