论文摘要
位于杰斐逊实验室的Gluex实验研究了在各种最终状态下使用光生生产的光生生产的黑龙的光谱。由于其检测器系统能够在几乎完整的实体角度测量中性和带电的最终状态颗粒，并且粒子识别能力非常好，因此Gluex可以测量许多含有陌生性的不同的Hadron。线性极化光子光束允许测量极化可观察物，其中包含有关在光生物中产生奇怪颗粒所涉及的生产机制的信息。此外，Gluex可以执行精确的横截面测量值，这有助于研究奇怪的Hadron的光谱。在本演讲中，引入了Gluex实验，并讨论了其陌生计划的最新进展。我们在$σ^0 $ beam beam不对称，$λ$（1520）旋转密度元素元素以及$λ$（1405）线形的持续研究中介绍了最新结果。我们还介绍了我们最近在$λ\barλ$和$ξ^{（*）} $ PHOTOPRODUCTION的测量方面的进展。同样，讨论了Gluex的陌生测量前景。
The GlueX experiment located at Jefferson Lab studies the spectrum of hadrons using photoproduction on a LH$_2$ target in a wide variety of final states. With its detector system capable of measuring neutral and charged final state particles over almost the full solid angle, and very good particle identification capabilities, GlueX can measure many different hadrons containing strangeness. A linearly polarized photon beam allows the measurement of polarization observables, which contain information about the production mechanisms involved in generating strange particles in photoproduction. In addition, GlueX can perform precise cross-section measurements, which help to study the spectrum of strange hadrons. In this presentation, the GlueX experiment is introduced, and recent progress of its strangeness program is discussed. We present recent results on $Σ^0$ beam asymmetries, $Λ$(1520) spin-density matrix elements and ongoing studies of the $Λ$(1405) lineshape. We also present our recent progress on measurements of $Λ\barΛ$ and $Ξ^{(*)}$ photoproduction. Also, future prospects for strangeness measurements at GlueX are discussed.
