论文摘要
我们重点介绍了超声光谱中的主题问题，当在JLAB计划咨询委员会提议的Jefferson Lab的D Hall D中创建了中性Kaons的次要光束。新光束的通量为$ 10^4 $ $ k_l $/s。反应产物将在Gluex实验设置中进行分析。我们指出需要回答哪些物理问题，并提出许多新颖的实验。特别是，我们建议测量$λ（1405）$的当前有争议的SU（3）结构，以搜索Pentaquarks Mit Exotic量子数字，并搜索属于SU（6）20-20-tepet代表的Baryons。
We highlight topical issues in hyperon spectroscopy that will be accessible when a secondary beam of neutral kaons is created in Hall D at Jefferson Lab as proposed to the JLab Program Advisory Committee. The new beam will have a flux of $10^4$ $K_L$/s. The reaction products will be analyzed in the GlueX experimental setup. We point out which physical questions need to be answered and suggest a number of novel experiments. In particular we suggest to measure the presently disputed SU(3) structure of the $Λ(1405)$, to search for Pentaquarks mit exotic quantum numbers and to search for baryons belonging to the SU(6) 20-plet representation.
