在这项研究中，我们分析了 LHCb 五夸克态的电产生，假设它们是共振态。我们主要关注的是研究相空间中的最终状态分布，以从大的非共振背景中提取微弱的五夸克信号。结果表明，通过适当的运动学切割，信号背景比将显着增加，这将有利于未来的实验分析。
In this study, we analyze the electroproduction of the LHCb pentaquark states with the assumption that they are resonant states. Our main concern is to investigate the final state distribution in the phase space to extract a feeble pentaquark signal from a large non-resonant background. The results indicate that the signal to background ratio will increase significantly with a proper kinematic cut, which will be beneficial for future experimental analysis.
