Description
The top quark spin information is highly correlated with the final state lepton polarization, making the dileptonic $t\bar{t}$ events good candidates to study quantum entanglement at the LHC. The $t\bar{t}$ momentum reconstruction is a key ingredient to accurately assessing such measurements. We will be comparing the strengths and weaknesses of different top-quark momentum reconstruction methods. We will then discuss a necessary and sufficient condition to define entanglement for the dileptonic $t\bar t$ events, and compare the reconstructed entanglement information.
