Observation of quantum entanglement in top-quark pair production using $pp$ collisions of $\sqrt{s} = 13$~\TeV\ with the ATLAS detector
We report the highest-energy observation of entanglement so far in top--antitop quark events produced at the Large Hadron Collider, using a proton$-$proton collision data set with a centre-of-mass energy of $\sqrt{s}=13$ TeV and an integrated luminosity of 140 fb$^{-1}$. Spin entanglement is detecte...
