论文摘要
已经进行了一项可行性研究,以调查Hades探测器的性能,以测量超子共振的$σ(1385)^0 $,$λ(1405)$和$λλ(1520)$的电磁衰变,以及p+p peam+p peam g kin的产生,以及双nyvers $ cyp peless $ c $ c kin的产生。现有的Hades探测器将通过新的前向检测器进行升级,该检测器将检测器的接受度扩展到一系列极地角度,这些范围对这些研究起着至关重要的作用。在每个通道的分析之前,请考虑生产横截面。之后,总结了使用由液体氢或聚乙烯组成的目标的预期信号计数速率。
A feasibility study has been performed in order to investigate the performance of the HADES detector to measure the electromagnetic decays of the hyperon resonances $Σ(1385)^0$, $Λ(1405)$ and $ΛΛ(1520)$ as well as the production of double strange baryon systems $Ξ^-$ and $ΛΛ$ in p+p reactions at a beam kinetic energy of 4.5 GeV. The existing HADES detector will be upgraded by a new Forward Detector, which extends the detector acceptance into a range of polar angles that plays a crucial role for these investigations. The analysis of each channel is preceded by a consideration of the production cross-sections. Afterwards the expected signal count rates using a target consisting of either liquid hydrogen or polyethylene are summarized.
