Quantum probes of invisible particles in top-quark pair production at the LHC
Top-quark pair production at the LHC provides a bipartite spin system whose correlations are imprinted in the angular distributions of the decay products and can be studied with quantum-information tools. We investigate whether this spin structure can be used to probe invisible new physics in $pp\to t\bar t+X$, where $...
