W Boson

Weak force mediator responsible for radioactive beta decay.

Core Principles & Analysis

• Discovered at CERN's Super Proton Synchrotron in 1983 by the UA1 and UA2 experiments.
• Mediates beta decay by transforming a down quark into an up quark.
• CDF's anomalous 2022 mass measurement was countered by 2024 CMS results agreeing with the Standard Model.
