论文摘要
我们探讨了最后一代的$ρ$（770）和$ k^*$（892）的共振，在E+Au Reactions在E $ _ \ Mathrm {lab} = 1.23 $ 〜Agev中通过Hadronic Channel使用URQMD模型在Hadronic Channel中的重建。这种共振研究允许以对Di-Lepton或HBT研究的互补方式获得有关此类反应的详细信息。我们观察到一个冻结的层次结构，并预测$ρ$（770）共振的质量变化（$Δm_ρ\约-330 $ meV）和$ k^*$（892）共振（$Δm__{k^*} \ y MEV）。这些质量转移与每个共振物种的再生周期有关，并且纯粹具有动力学。在实验上，我们的预测可以使用GSI-HADES实验或最低的Rhic-Bes能量进行测试。
We explore the properties of the last generation of $ρ$(770) and $K^*$(892) resonances created in Au+Au reactions at E$_\mathrm{lab}=1.23$~AGeV via the reconstruction in the hadronic channel using the UrQMD model. Such resonance studies allow to obtain detailed information on the emission source in such reactions in a complementary way to di-lepton or HBT studies. We observe a freeze-out hierarchy and predict mass shifts for the $ρ$(770) resonance ($Δm_ρ\approx -330$ MeV) and the $K^*$(892) resonance ($Δm_{K^*} \approx -30$ MeV). These mass shifts are related to the regeneration cycles of each resonance species and are of purely kinetic origin. Experimentally our predictions can be tested using the GSI-HADES experiment or the lowest RHIC-BES energy.
