论文摘要
在过去的几年中,我们对核中核子短距离相关(SRC)配对的理解取得了巨大进步,其中很大程度来自电子散射实验,导致SRC对破裂。这些实验的解释取决于对反应机理的假设。可以通过使用替代探针(例如实际光子)研究SRC对直接测试这些假设。我们在其标准配置中提出了使用D Hall D光子束,核目标和Gluex探测器的30天实验,以研究与光子诱导的反应的短距离相关性。可能的几个不同的反应通道是可能的,我们在大多数通道中的敏感性等于或超过了A和B厅的6个GEV时代的SRC实验。因此,提出的实验将决定性地测试NP优势的现象,短距离NN相互作用的现象,以及反应理论,同时还可以为界面结构和色彩透明度提供新的洞察力。
The past few years has seen tremendous progress in our understanding of short-range correlated (SRC) pairing of nucleons within nuclei, much of it coming from electron scattering experiments leading to the break-up of an SRC pair. The interpretation of these experiments rests on assumptions about the mechanism of the reaction. These assumptions can be directly tested by studying SRC pairs using alternate probes, such as real photons. We propose a 30-day experiment using the Hall D photon beam, nuclear targets, and the GlueX detector in its standard configuration to study short-range correlations with photon-induced reactions. Several different reaction channels are possible, and we project sensitivity in most channels to equal or exceed the 6 GeV-era SRC experiments from Halls A and B. The proposed experiment will therefore decisively test the phenomena of np dominance, the short-distance NN interaction, and reaction theory, while also providing new insight into bound nucleon structure and the onset of color transparency.
