标题： Research News -- Quantum Mechanical Entanglement and Tests of CPT Theorem with Neutral Mesons at e+ e- Colliders

摘要： 我们回顾了在日本KEK-B的BELLE实验以及在意大利DAFNE的KLOE实验中关于正负电子湮没产生中性B介子和K介子系统中量子纠缠的近期确认。后者系统中这类效应已在质子-反质子碰撞中由CPLEAR实验观测到，本文也进行了回顾以便比较。此外，KLOE实验还提供了CPT定理的新检验，并简要讨论了相关结果。 显示英文摘要

摘要： We review the recent confirmation of quantum entanglement in e+ e- collisions at the BELLE experiment at KEK-B in Japan with neutral B- mesons, and at the KLOE experiment at the DAFNE in Italy with neutral K- mesons. Such effects in the latter system seen already in proton-antiproton collisions by the CPLEAR experiment are also reviewed for purposes of comparison. In addition, the KLOE experiment provides new tests of the CPT theorem and are briefly discussed.
