论文摘要
近几十年来,由新的高亮度实验驱动,对强子光谱的兴趣重新浮现,这些实验已经确定了许多新的Hadron,既预期又出乎意料。大量意外的哈德子表明,除了基本夸克模型之外,其他Quark和Gluonic自由度的贡献。由于在新的和计划中的实验设施中可访问的状态范围,在其他实验中,降低了阈值附近的效果以及我们对这些反应的理论理解的进步,因此,光生源已成为研究HADRON光谱法的一个有吸引力的过程。这份白皮书回顾了三个主要现有和拟议的设施的强子光谱的前景:当前的Gluex实验,计划中的电子离子对撞机以及拟议的JLAB 24 GEV升级。
Recent decades have seen a resurge of interest in hadron spectroscopy, driven by new, high-luminosity experiments which have identified many new hadrons, both expected and unexpected. The large number of unexpected hadrons suggest contributions from additional quark and gluonic degrees of freedom to the hadronic spectrum beyond the basic quark model. Photoproduction has emerged as an attractive process to study hadron spectroscopy, due to the range of states accessible in new and planned experimental facilities, complimentary kinematics to other experiments where rescattering effects near thresholds are reduced, and advances in our theoretical understanding of these reactions. This white paper reviews the prospects for hadron spectroscopy from three major existing and proposed facilities: the current GlueX experiment, the planned Electron-Ion Collider, and a proposed JLab 24 GeV upgrade.
