中子衰变的逆Zeno效应模型

Modelling the inverse Zeno effect for the neutron decay

Francesco Giacosa

摘要:

射束法和阱法发现中子寿命的结果不一致:前者的值比后者长约$8.7\pm2.1$ s。最近(1906.10024),有人提出,逆芝诺效应(IZE)可能是负责较短的寿命在陷阱实验。在这里,我们比较了两种不同的测量模型,一种是通过砰砰测量和连续测量获得的:事实证明,在这两种情况下IZE非常相似,这表明结果不取决于测量过程的细节。

英文摘要:

Beam and trap methods find incompatible results for the lifetime of the neutron: the former delivers a value which is about $8.7\pm2.1$ s longer than the latter. Very recently (1906.10024) it has been proposed that the inverse Zeno effect (IZE) could be responsible for the shorter lifetime in trap experiments. Here, we compare two different models of measurement, one obtained by bang-bang measurements and by a continuous measurement: the IZE turns out to be in both cases very similar, showing that the results do not depend on the details of the measurement process.
