摘要:

对中子寿命实验进行了详细的分析和蒙特卡罗模拟[S. Arzumanov等人,Phys. Lett. B 483(2000)15],因为该实验的结果与我们的实验[A. Serebrov等人,Phys. Lett. B 605(2005)72]。我们发现了一些在实验中没有考虑到的影响[S. Arzumanov等人,Phys. Lett. B 483(2000)15]。可能的校正为-5.5 s,不确定度为2.4 s,这来自初始数据知识。我们假设,在考虑了这种修正后,工作的结果[S。Arzumanov等人,Phys. Lett. B 483(2000)15]的中子寿命885.4 +/- 0.9stat +/- 0.4syst s可校正为879.9 +/- 0.9stat +/- 2.4syst s。

英文摘要:

We performed a detailed analysis and the Monte Carlo simulation of the neutron lifetime experiment [S. Arzumanov et al., Phys. Lett. B 483 (2000) 15] because of the strong disagreement by 5.6 standard deviations between the results of this experiment and our experiment [A. Serebrov et al., Phys. Lett. B 605 (2005) 72]. We found a few effects which were not taken into account in the experiment [S. Arzumanov et al., Phys. Lett. B 483 (2000) 15]. The possible correction is -5.5 s with uncertainty of 2.4 s which comes from initial data knowledge. We assume that after taking into account this correction the result of work [S. Arzumanov et al., Phys. Lett. B 483 (2000) 15] for neutron lifetime 885.4 +/- 0.9stat +/- 0.4syst s could be corrected to 879.9 +/- 0.9stat +/- 2.4syst s.
