Abstract

The results of searches for the process \(e^{+}e^{-}\to\eta^{\prime}\gamma\) in an experiment with the SND detector at the VEPP-2000 electron–positron collider are presented. The data used in these searches and based on an integrated luminosity of about 87 pb\({}^{-1}\) were accumulated at c.m. energies \(\sqrt{s}\) between 1.15 and 2 GeV. The upper limits of \(\sigma_{\eta^{\prime}\gamma}<28\) pb for \(1.15<\sqrt{s}<1.39\) GeV and \(\sigma_{\eta^{\prime}\gamma}<12\) pb for \(1.39<\sqrt{s}<2.00\) GeV were set at a 90\(\%\) confidence level.

使用SND检测器搜索过程$$ {e} ^ {+} {e} ^ {-} \到\ eta ^ {\ prime} \ gamma $$

摘要

呈现了在VEPP-2000电子-正负电子对撞机上使用SND检测器进行的实验中搜索过程\(e ^ {+} e ^ {-} \ to \ eta ^ {\ prime} \ gamma \)的结果。 。这些搜索中使用的数据,基于约87 pb \({} ^ {-1} \)的综合亮度,在1.15和2 GeV之间的cm能量\(\ sqrt {s} \)处累积。\(1.15 <\ sqrt {s} <1.39 \) GeV和\(\ sigma _ {\ eta ^ {\ eta ^ {\\ sigma _ {\ eta ^ {\ prime} \ gamma} <28 \) pb的上限\(1.39 <\ sqrt {s} <2.00 \) GeV的质数} \ gamma} <12 \) pb设置为90 \(\%\)的置信度。
