Researchers at CERN's LHC, through CMS and ATLAS experiments, have observed a fleeting bound state of top quark and antiquark pairs, called toponium, challenging previous assumptions about the top quark's behavior and opening new avenues for understanding the strong nuclear force and potential new particles.
John Peoples, a key figure in particle physics and former director of Fermilab during the discovery of the top quark and the Tevatron's prominence, passed away at age 92. He contributed significantly to Fermilab's research and leadership, including the development of the antiproton source and supporting astrophysics programs.
The ATLAS Collaboration at CERN's Large Hadron Collider has observed the coincident production of a single top quark and a photon in proton-proton collisions. This observation provides valuable insights into the electroweak interaction of the top quark, the heaviest known fundamental particle. The measurement suggests a higher rate of production than predicted by the standard model, indicating potential deviations and the possibility of new particles. Further analysis and data collection will help uncover the properties of these events and their implications for physics beyond the standard model.
