The new value, presented in March at the Rencontres de Moriond, contradicts CDF measurement published last year.
A team of researchers at CERN’s Large Hadron Collider have measured the mass of the W boson and found it to be in line with the Standard Model of
Does the W boson break the Standard Model? Depends on how you measure it.
Last year a new finding in particle physics stunned scientists: a fundamental particle responsible for one of the Universe's four fundamental forces was heavier than predicted.
A new and improved look at the mass of the W boson is in close alignment with theory, but it doesn’t negate an earlier, controversial measurement.
