用两种不同的方法研究了核介质中矢量介子的质量移动：介质中QCD求和规则方法和散射长度方法。后者不适用于提取介质中的强子质量。本文还讨论了介质内QCD求和规则的进一步阐述。
Mass shift of vector mesons in the nuclear medium is studied in two different approaches: the in-medium QCD sum-rule approach and the scattering-length approach. The latter is shown to be inapplicable to extract the hadron masses in the medium. Further elaboration of the in-medium QCD sum rules is also discussed.
