W Boson Measurement Challenges the Standard Model
A recent measurement of a fundamental particle called the W boson appears to defy the Standard Model of particle physics, our current understanding of how the basic building blocks of the universe interact.
- The scientists at the Fermilab Collider Detector (CDF) in Illinois, USA have found that elusive W boson has a slightly (1%) higher mass (80,433,000 electron volts) than predicted in the Standard Model (80,357,000 electron volts).
- The difference is tiny but in the world of particle physics, it is a huge anomaly. This means that the Standard Model may be in for a massive overhaul.
