Search for exotic mesons at GlueX

奇异介子的存在是核物理界和粒子物理界争论不休的话题。我们目前的强相互作用模型预测的这种类型的粒子，还没有完全建立起来。它的存在(或不存在)对我们目前对夸克和胶子如何相互作用的理解有很大影响。这项研究项目将为GlueX合作正在进行的努力做出贡献。GlueX是一项致力于寻找奇异介子的实验。在过去的四年里，收集了大量的光生产数据集。高能光子和质子之间的这些相互作用产生了各种各样的粒子，其衰变产物是在GlueX探测器装置中测量的。光产生也有望产生奇异的介子，尽管可能性很小。因此，为了发现隐藏在大量普通介子下的微小信号，仔细分析数据是至关重要的。这需要使用创新的数据分析技术。该项目将探索使用人工智能来增强我们寻找奇异介子的能力的可能性，以及扩展目前使用的贝叶斯分析技术。开发这些有前景的方法将有助于GlueX和未来更广泛的强子光谱学社区，不仅是为了寻找奇异的粒子，而且是为了总体上寻找新的粒子。

The existence of exotic mesons is a highly debated topic in the nuclear and particle physics communities. This type of particle, which is predicted by our current model of the strong interaction, has not been fully established, yet. It's existence (or absence) has a large impact on our current understanding of how quarks and gluons, the building blocks of matter, interact.This research project will contribute to the ongoing efforts of the GlueX collaboration. GlueX is an experiment dedicated to the search for exotic mesons. Over the past four years large photoproduction data sets of were collected. These interactions between high energy photons and protons create a large variety of particles, whose decay products are measured in the GlueX detector setup. Photoproduction is also expected to produce exotic mesons, albeit with a small probability. For this reason, a careful analysis of the data is crucial in order to uncover the tiny signals hidden under the vast number of ordinary mesons. This requires the use of innovative data analysis techniques. The project will explore the possibilities to use artificial intelligence to enhance our capabilities in the hunt for exotic mesons as well as expand on currently used Bayesian analysis techniques. Developing these promising methods will help GlueX and the wider hadron spectroscopy community in the future, not only for the search for exotic particles, but for new particles in general.
