标题： P371 Experiment at CERN - quest for polarized antiprotons

摘要： 质子反粒子在CERN PS束流线T11处3.5 GeV/c下的产生中的极化效应已在P371实验中进行了研究。 这些效应，如果被发现是显著的，可以提供一种利用现有设施生成极化反质子束的简单方法。 P349合作组首先进行了前导测量，尽管可用统计数据不足以得出定量结论。 通过升级的探测器设置和延长的束流时间，该实验旨在确定是否存在可测量的反质子极化程度。 显示英文摘要

摘要： Polarization effects in the production of antiprotons at the CERN PS beam line T11 at 3.5 GeV/c have been investigated within the P371 experiment. These effects, if found to be significant could provide a simple method to generate polarized antiproton beams with existing facilities. First precursor measurements were carried out by the P349 collaboration, though the available statistics were insufficient for a quantitative conclusion. With an upgraded detector setup and extended beam time, the experiment aims at determining whether a measurable degree of antiproton polarization exists.
