摘要

在81 cm的Saclay氢泡腔中，对1.18 GeV/c的2764次反质子双散射事件进行了分析，得出在15°±θc.m角区域的不对称性为(−2.3±3)%。≥60°，平均角度θ cm。= 28°。这将对应于反质子极化在95%置信限的20%的上限。

Study of the polarization of antiproton in pp scattering at 1.18 GeV/c

Analysis of 2764 double scattering events of antiprotons at 1.18 GeV/c in the 81 cm Saclay hydrogen bubble chamber yields an asymmetry of (−2.3±3)% for the angular region 15° ⩽ θ_c.m. ⩽ 60°, with an average angle θ_c.m. = 28°. This would correspond to an upper limit of 20% for the polarization of the antiproton at 95% confidence limit.
