Top quark spin and quantum entanglement in the ATLAS experiment
Abstract
Top quark pair spin correlation measurements performed by the ATLAS experiment using pp p p collisions at the CERN Large Hadron Collider are summarized. Moreover, the measurement of a specific observable D D related to top quark pair spin correlations is presented using the full LHC Run 2 data taking at the center-of-mass energy of \sqrt{s} = 13 s = 13 ~TeV. This allowed the ATLAS experiment to observe the quantum entanglement, one of the fundamental property of the quantum mechanics.
