Overview
The W boson mass discrepancy between the CDF-II measurement (80.4335 GeV) and the Standard Model prediction was one of the most discussed anomalies in particle physics. The τ-framework predicts m_W at −0.5 ppm from the current world average.
Result Statement
m_W predicted at −0.5 ppm from the world average, derived from the electroweak sector template. Zero free parameters. Status: Resolved.
