A critical appraisal of tests of locality and of entanglement versus non-entanglement at colliders

Philip Bechtle, Cedric Breuning, Herbi K. Dreiner +1

It has been argued more than 30 years ago that it is not possible to test locality at colliders, due to the inability to directly measure non-commutating observables such as spin c…

Prospects of measuring quantum entanglement in $I ¨ I ¨ $ final states at a future $e^{+} e^{-}$ Higgs factory

Cedric Breuning, Philip Bechtle, Klaus Desch +1

We introduce a method to study quantum entanglement at a future $e^{+} e^{-}$ Higgs factory (here the Future Circular Collider colliding $e^{+}$ and $e^{-}$ (FCC-ee) operating at $\sqrt{s}=…
