在LHC上用顶夸克对检验贝尔不等式
Testing Bell inequalities at the LHC with top-quark pairs
摘要:
对撞机产生的顶夸克对自旋之间的纠缠可以用来检验迄今为止从未探索过的能量下的(广义)贝尔不等式。我们展示了如何测量一个单一的可观察到的可以提供一个测试的违反贝尔不等式在98%CL的数据已经收集在大型强子对撞机和在99.99%CL与更高的亮度下一次运行。
英文摘要:
Entanglement between the spins of top-quark pairs produced at a collider can be used to test a (generalized) Bell inequality at energies never explored so far. We show how the measurement of a single observable can provide a test of the violation of the Bell inequality at the 98% CL with the data already collected at the Large Hadron Collider and at the 99.99% CL with the higher luminosity of the next run.
