用DIRC的BaBar元件研究D厅中含GlueX的奇异末态衰变
A study of decays to strange final states with GlueX in Hall D using components of the BaBar DIRC
摘要：
我们建议通过构建FDIRC（聚焦检测内部反射切伦科夫）探测器，利用退役的BaBar DIRC组件，以提高的GREX探测器的K介子识别能力。GSTX FDIRC将大大增强GSTX物理计划，允许人们搜索和研究衰变到K介子末态的混合介子。这种对K介子末态的系统研究对于推断混合介子和常规介子的夸克味含量是必不可少的。GABRIX FDIRC将重复使用BaBar DIRC中使用的三分之一的合成熔融石英棒。一种新的聚焦光子相机，读出与大面积光电探测器，将被开发。我们建议在D厅以5 × 10^7 γ/s的平均强度运行增强型GSTX探测器，总共220天，该计划已获得PAC 39的有条件批准
英文摘要：
We propose to enhance the kaon identification capabilities of the GlueX detector by constructing an FDIRC (Focusing Detection of Internally Reflected Cherenkov) detector utilizing the decommissioned BaBar DIRC components. The GlueX FDIRC would significantly enhance the GlueX physics program by allowing one to search for and study hybrid mesons decaying into kaon final states. Such systematic studies of kaon final states are essential for inferring the quark flavor content of hybrid and conventional mesons. The GlueX FDIRC would reuse one-third of the synthetic fused silica bars that were utilized in the BaBar DIRC. A new focussing photon camera, read out with large area photodetectors, would be developed. We propose operating the enhanced GlueX detector in Hall D for a total of 220 days at an average intensity of 5x10^7 γ/s, a program that was conditionally approved by PAC39
