CHORUS实验中中微子诱发双μ子事件的首阶分析

Leading order analysis of neutrino induced dimuon events in the CHORUS experiment

The CHORUS Collaboration

摘要:

我们提出了一个领先的阶QCD分析的中微子诱导的带电电流事件的样品中的两个μ子在最后的状态起源于铅的CHORUS检测器的光纤量热计。结果是基于8910中微子和430反中微子引起的相反符号的双μ子事件收集的检测器在1995年和1998年之间的欧洲核子研究中心的宽带中微子束曝光的样本。1995年至1998年期间收集的$E_{μ1},E_{μ2} > 5$ GeV和$Q^2 > 3$ GeV $^2$的%。分析得到了$\mc = (1.26\pm 0.16 \pm 0.09) \GeVcc $的粲夸克质量和$κ= 0.33 \pm 0.05 \pm 0.05$的核子中奇异海与非奇异海的比值,改进了以前实验中类似分析的结果。

英文摘要:

We present a leading order QCD analysis of a sample of neutrino induced charged-current events with two muons in the final state originating in the lead-scintillating fibre calorimeter of the CHORUS detector. The results are based on a sample of 8910 neutrino and 430 antineutrino induced opposite-sign dimuon events collected during the exposure of the detector to the CERN Wide Band Neutrino Beam between 1995 and 1998. % with $E_{μ1},E_{μ2} > 5$ GeV and $Q^2 > 3$ GeV$^2$ collected %between 1995 and 1998. The analysis yields a value of the charm quark mass of $\mc = (1.26\pm 0.16 \pm 0.09) \GeVcc $ and a value of the ratio of the strange to non-strange sea in the nucleon of $κ= 0.33 \pm 0.05 \pm 0.05$, improving the results obtained in similar analyses by previous experiments.
