A bstract The recent observation of entanglement between top and anti-top quarks at the LHC opens way to interpreting collider data with quantum information tools. In this work we investigate relevance observables in searches new physics. To aim, study spin correlations $$t\overline{t }$$ pairs originating from various intermediate resonances, compare discovery reach compared classical ones. We find that they provide complementary and, several notable cases, also additional leverage necessary detect effects.
