论文摘要
在我们之前的论文中报道了用富含Delphi枪管的富含Delphi枪管的反射率大于由超层状颗粒产生的搜索的结果[1]。该搜索是基于在LEP1和LEP2期间在CERN的Delphi合作收集的数据。对能够产生明显异常环的背景来源进行了详细研究；它表明背景假设的概率很低（$ 10^{ - 3} $或更少）。通过观察液体中的异常环半径与所选事件中的气态辐射器之间的高度相关性提供了反对背景假设的额外强烈论点。在本文中，根据观察更快的轻度颗粒（Tachyons）来解释所获得的结果。在此解释的框架内，观察到了$（0.29 \ pm 0.01）$ 〜GEV/c $^2 $和$（4.6 \ pm 0.2）$ 〜GEV/C $^2 $。 这项工作是由作者按照外部访问Delphi存档数据的规则进行的，如http://delphiwwwwwwwwwwwwwwwwwwwwwwww.cern.ch/delsec/delsec/finalrules/finalrules/finalrules011203.pdf 本材料中表达的观点，发现和结论仅是作者的观点，并且不会以任何方式反映Delphi合作的观点。
The results of a search with the DELPHI Barrel RICH for anomalous Cherenkov rings having radii greater than those produced by ultrarelativistic particles were reported in our previous paper [1]. The search was based on the data collected by the DELPHI Collaboration at CERN during the LEP1 and LEP2 periods. A detailed study of background sources capable of producing apparently anomalous rings has been done; it indicated that the background hypothesis has a low probability ($10^{-3}$ or less). An additional strong argument against the background hypothesis was provided by the observation of a high degree of correlation between anomalous ring radii in the liquid and gaseous radiators in the selected events.The results obtained are interpreted in this paper in terms of observation of faster-than-light particles (tachyons). In the framework of this interpretation two peaks in the tachyon mass parameter distribution are observed, at $(0.29 \pm 0.01)$~GeV/c$^2$ and $(4.6 \pm 0.2)$~GeV/c$^2$. This work has been performed by the authors following the rules for external access to the DELPHI archived data, as established in http://delphiwww.cern.ch/delsec/finalrules/FINALrules011203.pdf The opinions, findings and conclusions expressed in this material are those of the authors alone and do not reflect in any way the views of the DELPHI Collaboration.
