粒子衰变会引起波函数坍缩吗:实验检验

Does particle decay cause wave function collapse: An experimental test

Spencer R. Klein, Joakim Nystrand

摘要:

我们描述了一个粒子衰变是否会引起波函数坍缩的实验测试。该测试使用两个分离良好但相干的矢量介子源之间的干涉。短寿命的介子在它们的波函数可以重叠之前就衰变了,所以任何干涉都必须涉及相同的末态。与以前的非定域性测试不同,干扰涉及连续变量、动量和位置。只有当波函数在所有可能的衰变中都保持振幅时,才会发生干涉。这种干涉可以通过重构介子的横动量谱来研究。

英文摘要:

We describe an experimental test of whether particle decay causes wave function collapse. The test uses interference between two well separated, but coherent, sources of vector mesons. The short-lived mesons decay before their wave functions can overlap, so any interference must involve identical final states. Unlike previous tests of nonlocality, the interference involves continuous variables, momentum and position. Interference can only occur if the wave function retains amplitudes for all possible decays. The interference can be studied through the transverse momentum spectrum of the reconstructed mesons.
