Experimental characterization of the hierarchy of quantum correlations in top quark pairs
Yoav Afik, Regina Demina, Alan Herrera +3
Recent results from the Large Hadron Collider have demonstrated quantum entanglement of top quark-antiquark pairs using the spin degrees of freedom. Based on the doubly differentia…
ATLAS and CMS measurements of the cross section, including off-shell and near threshold
Baptiste Ravina
Recent measurements of the cross section, performed both inclusively and differentially by the ATLAS and CMS Collaborations, are reported. In particular, off-shell effec…
Quantum Information meets High-Energy Physics: Input to the update of the European Strategy for Particle Physics
Yoav Afik, Federica Fabbri, Matthew Low +68
Some of the most astonishing and prominent properties of Quantum Mechanics, such as entanglement and Bell nonlocality, have only been studied extensively in dedicated low-energy la…
Observation of quantum entanglement in top quark pairs at the ATLAS experiment
Baptiste Ravina
The ATLAS Collaboration has recently reported the first observation of quantum entanglement in top quark pair production at the Large Hadron Collider (LHC). A brief review of the e…
