Prospects of measuring quantum entanglement in $\tau \tau$ 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}=…
