我们于2018年在托马斯杰斐逊国家加速器设施（JLab）使用氚和氢低温气体靶进行了实验（E12-17-003）[1，2]。本文讨论了从氢靶上电产生Λ/Λ 0超子的问题。基本的Λ/Λ 0超子产生过程不仅对我们实验中的绝对质量刻度很重要，而且对研究电产生机制本身也很重要。本文报道了在Q ~ 2 = 0.5（GeV/c）~ 2时p（e，e 'K ~+）Λ/Λ ~ 0反应的微分截面的结果。
We performed an experiment using tritium and hydrogen cryogenic gas targets at Thomas Jefferson National Accelerator Facility (JLab) in 2018 (E12-17-003)[1, 2]. In this article, we discuss the Λ/Σ0hyperon electroproduction from hydrogen target. Elementary Λ/Σ0hyperon production processes are important not only for an absolute mass scale calibration in our experiment, but also for the study of the electroproduction mechanisms themselves. In this article, we reported the results of the differential cross section for thep(e,e’K+)Λ/Σ0reaction atQ2∼ 0.5 (GeV/c)2.
