GSI时间异常:事实与虚构

The GSI Time Anomaly: Facts and Fiction

Carlo Giunti

摘要:

反驳了GSI时间异常是由于中微子在观测到的电子俘获过程的最终状态中混合的说法。借助于与双缝实验的类比,证明了把所有允许的末态的产生率相加来计算相互作用过程速率的标准方法是正确的,而不管它们之间是否存在相干性。这是因果关系的结果。结果表明,GSI时间异常可能是由于存在两个相干能级的衰变离子与一个非常小的能量分裂(约$6\times10^{-16} \text{eV}$)和相对概率约为1/99的量子拍。

英文摘要:

The claims that the GSI time anomaly is due to the mixing of neutrinos in the final state of the observed electron-capture processes are refuted. With the help of an analogy with a double-slit experiment, it is shown that the standard method of calculation of the rate of an interaction process by adding the rates of production of all the allowed final states, regardless of a possible coherence among them, is correct. It is a consequence of causality. It is shown that the GSI time anomaly may be caused by quantum beats due to the existence of two coherent energy levels of the decaying ion with an extremely small energy splitting (about $6\times10^{-16} \text{eV}$) and relative probabilities having a ratio of about 1/99.
