Description
Measurements of top quark spin observables in ttbar events represents a unique possibility to test the standard model (SM) predictions and probe the new physics effects. Potential deviations from the SM expectations are parametrised within the framework of the Effective Field Theory (EFT). In this presentation, we introduce how to measure the spin correlation between top quarks and we cover the impact of introducing dimension-six operators spin observables. Furthermore, we present the first proposal for detecting entanglement in a pair of quarks , as well as the violation of Bell inequalities (BIs) at LHC.
