| Özet |
| Entanglement is an intrinsic property of quantum mechanics and is predicted to be exhibited in the particles produced at the Large Hadron Collider. A measurement of the extent of entanglement in top quark-antiquark ( tt¯) events produced in proton–proton collisions at a center-of-mass energy of 13 TeV is performed with the data recorded by the CMS experiment at the CERN LHC in 2016, and corresponding to an integrated luminosity of 36.3 fb−1. The events are selected based on the presence of two leptons with opposite charges and high transverse momentum. An entanglement-sensitive observable D is derived from the top quark spin-dependent parts of the tt¯ production density matrix and measured in the region of the tt¯ production threshold. Values of D<−1/3 are evidence of entanglement and D is observed (expected) to be −0.480−0.029+0.026 ( −0.467−0.029+0.026) at the parton level. With an … |
