Kurzfassung

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 $\sqrt{s} = 240 GeV$) in the $\tau\tau$ final state. This method is focused on the $\tau\to\pi\nu_\tau$ decay. We show how the introduced method works on simulated events without detector effects. When detector effects are applied, the necessary $\tau$ four-momenta can be reconstructed from kinematic constraints. We will discuss the advantages of e+e− collisions over pp collisions where the reconstruction of the $\tau\tau$ rest frame is more difficult. This discussion will focus on the influence of $p_T$ trigger cuts on the visible $\pi^\pm$ in the $\tau$ lepton decay.
