New Measurement of W Boson Mass Aligns with Standard Model of Particle Physics

Researchers have measured the mass of the W boson at 80.360 ± 0.008 GeV, consistent with predictions from the standard model. This result comes from data collected by the ATLAS detector at CERN's Large Hadron Collider. The finding contradicts a 2022 measurement from the Fermilab…
