Summary

Story summary

The Large Hadron Collider at CERN has observed tWZ production, a process involving a single top quark with W and Z bosons, for the first time.
This phenomenon occurs once in every trillion proton collisions.
The Compact Muon Solenoid (CMS) collaboration used advanced machine learning to isolate the tWZ signal from more common processes.
The finding could yield insights into the Higgs mechanism and physics beyond the Standard Model.
