Abstract

Quantum entanglement, a fundamental feature of quantum mechanics, has become a powerful tool impacting various areas of physics. In this proceeding, we investigate the presence of quantum entanglement within the Higgs to ZZ* (HZZ*) interaction at the ATLAS experiment. Utilizing quantum tomography techniques, we extract the complete spin density matrix characterizing the HZZ* interaction from ATLAS Standard Monte Carlo (MC) HZZ* 4l Run2 samples. We then evaluate the presence of quantum entanglement in the system using the derived spin density matrix. Our investigation sheds light on the entanglement properties within the HZZ* interaction, which offers valuable insights into its quantum characteristics.
