Test of quantum nonlocality via vector meson decays to KSKS

In the system of a pair of quantum-entangled neutral kaons from meson decays, when one kaon collapses into the K_Sstate, the other will collapse instantaneously into the K_Lstate due to entanglement and nonlocality. However, if the alternative hypothesis is correct and there's a time window during which one kaon is unaware that the other has decayed, some quantum mechanically prohibited K_SK_Sdecays may occur. We calculate the branching...
