时变核衰变参数与暗物质

Time-Varying Nuclear Decay Parameters and Dark Matter

Jonathan Nistor, Ephraim Fischbach, John T. Gruenwald, Daniel Javorsek, Jere H. Jenkins, Robert H. Lee

摘要:

最近公布的数据表明,太阳可能影响某些核衰变率,包括地球与太阳距离的变化导致的年度变化的证据。在这里,我们认为DAMA合作所看到的年度信号的可能性,并解释为暗物质的证据,实际上可能是由于放射性污染物K-40,这是已知的存在于他们的检测器。我们还考虑了部分DAMA信号可能来自遗留大爆炸中微子的可能性。

英文摘要:

Recently published data suggest a possible solar influence on some nuclear decay rates, including evidence for an annual variation attributed to the varying Earth-Sun distance. Here, we consider the possibility that the annual signal seen by the DAMA collaboration, and interpreted by them as evidence for dark matter, may in fact be due to the radioactive contaminant K-40, which is known to be present in their detector. We also consider the possibility that part of the DAMA signal may arise from relic big-bang neutrinos.
