论文摘要
对电磁探针实验的黑龙的光谱及其结构的研究为大型夸克 - 丝线连续耦合的稳定相互作用的许多方面提供了独特的见解,{\ it I.e。}强QCD的制度。基于用电子和光子梁获得的数据,在实验和现象学数据分析之间的联合工作中,使用电子和光子束在杰斐逊实验室内的实验计划基于使用电子和光子束获得的数据。在过去的十年中,已经实现了从数据推断到强大的强子产生的强大QCD机制的强调结构可观察到的令人印象深刻的进展。这些结果将通过实验程序中的数据大大扩展,并使用新的CLAS12光谱仪使用具有高达11 gEV的电子束开始吸收数据。借助这种扩展的运动范围,将以独家电气导染的研究中有史以来最高的光子虚拟性进行探测,这将允许探索距离尺度的探索,在这种距离中,$ 98 \%的$ 98 \%的轻型强子质量从QCD中出现在QCD中,从QCD中出现,从而在与Quark-Gluon pertive pertime pertuft pertuft pertuff pertuff pertuff pertuff pertime qcd pertaction中的过渡中相互作用。
Studies of the spectrum of hadrons and their structure in experiments with electromagnetic probes offer unique insight into many facets of the strong interaction in the regime of large quark-gluon running coupling, {\it i.e.} the regime of strong QCD. The experimental program within Hall~B at Jefferson Laboratory based on data acquired with the CLAS spectrometer using electron and photon beams with energies up to 6~GeV has already considerably extended the scope of research in hadron physics in joint efforts between experiment and phenomenological data analysis. Impressive progress in relating the hadron structure observables inferred from the data to the strong QCD mechanisms underlying hadron mass generation has been achieved in the past decade. These results will be considerably extended with data from the experimental program with the new CLAS12 spectrometer that has begun data taking using electron beams with energies up to 11~GeV. With this extended kinematic reach the structure of nucleon resonances will be probed at the highest photon virtualities ever achieved in the studies of exclusive electroproduction, which will allow for the exploration of the distance scale where $>$98\% of light hadron mass emerges from QCD in the transition of the strong interaction from the regime of quark-gluon confinement to perturbative QCD.
