超子和级联重子的光谱学研究
Highlights of the Spectroscopy of Hyperons and Cascade Baryons
摘要：
我们强调超子光谱学中的热点问题，将访问时，在杰斐逊实验室的D厅创建的中性K介子的二次光束的JLab计划咨询委员会的建议。新光束的通量为$10^4$ $K_L$ /s。反应产物将在GSTX实验装置中进行分析。我们指出哪些物理问题需要回答，并提出了一些新颖的实验。特别是我们建议测量目前有争议的SU（3）结构的$Λ(1405)$，寻找五夸克与奇异的量子数和寻找属于SU（6）20重态表示的重子。
英文摘要：
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.
