Abstract

We discuss the time evolution of quantum entanglement in the presence of non-collapsing interactions. In particular, the entanglement between the products of a muon decay in a magnetic field is revisited. It results from angular momentum conservation and leads to an anomaly in the measured muon g factor in precise agreement with that reported by the Brookhaven and Fermilab experiments, alleviating the present tension between data-driven and lattice theoretical values.

介子衰变中的相对论纠缠

我们讨论了在非坍缩相互作用下量子纠缠的时间演化。特别地，在磁场中介子衰变产物之间的纠缠被重新审视。它源于角动量守恒，导致测量到的μ子g因子异常，与布鲁克海文和费米实验室实验报告的结果完全一致，缓解了目前数据驱动和晶格理论值之间的紧张关系。

期刊介绍： The Brazilian Journal of Physics is a peer-reviewed international journal published by the Brazilian Physical Society (SBF). The journal publishes new and original research results from all areas of physics, obtained in Brazil and from anywhere else in the world. Contents include theoretical, practical and experimental papers as well as high-quality review papers. Submissions should follow the generally accepted structure for journal articles with basic elements: title, abstract, introduction, results, conclusions, and references.
