摘要:

本文报道了在有限重子密度下ρ介子和Ω介子的介质内谱函数的自洽计算。产生了相应的介质双轻子谱,并与HADES数据进行了比较。我们发现,迭代计算的矢量介子谱函数提供了一个合理的描述的实验数据。

英文摘要:

We report on a self-consistent calculation of the in-medium spectral functions of the rho and omega mesons at finite baryon density. The corresponding in-medium dilepton spectrum is generated and compared with HADES data. We find that an iterative calculation of the vector meson spectral functions provides a reasonable description of the experimental data.
