DESCRIPTION:Speakers: J.A. Aguilar-Saavedra\, Jeffrey Davis (Johns Hopkins
  University (US))\n\nAbstractThe Standard Model of particle physics is a q
 uantum field theory\, based on quantum mechanics and special relativity. C
 ollider processes allow us to test fundamental properties of quantum mecha
 nics. Higgs decays H → ZZ → 4 leptons are a unique high-energy system 
 in which spin entanglement is predicted to be nearly maximal\, and spin co
 rrelations can be cleanly measured. Thus\, it is possible to study fundame
 ntal aspects of quantum mechanics such as entanglement. We will discuss th
 e theoretical background\, the spin correlation measurements by the ATLAS 
 and CMS Collaborations and their consequences in terms of entanglement and
  particle indistinguishability.\nSpeakers\nJeff Davis is a post-doctoral f
 ellow at Johns Hopkins University. He received his PhD from Johns Hopkins 
 in late 2025. Jeff is a member of the CMS collaboration where he works on 
 measuring the properties of the Higgs boson using the four-lepton final st
 ate. His primary research interests are in effective field theory interpre
 tations of Higgs boson and electroweak vector boson data\, as well using H
 iggs decays to test the fundamental aspects of quantum mechanics.\n \nJua
 n Antonio Aguilar Saavedra is a scientific researcher at CSIC (IFT/Madrid)
  since 2021\, and associate professor on leave from the University of Gran
 ada. He obtained his PhD at the University of Granada\, moved to Instituto
  Superior Técnico of Lisbon as a post-doc for 4 years\, and returned to G
 ranada where he taught for 15 years. He has worked on top quark physics\, 
 beyond-the-SM theories with vector-like quarks and leptons\, effective fie
 ld theory\, jet tagging and anomaly detection\, ambulance chasing\, and in
  the last four years in tests of quantum foundations in high-energy physic
 s\, namely bipartite and tripartite entanglement\, Bell nonlocality\, iden
 tical-particles\, and quantum interference effects.\n \n\nhttps://indico.
