Measurements of polarization and spin correlation and observation of entanglement in top quark pairs using lepton+jets events from proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

Measurements of the polarization and spin correlation in top quark pairs ($\mathrm{t}\bar{\mathrm{t}}$) are presented using events with a single electron or muon and jets in the final state…
