World's Best Measurement of W Boson Mass Points to Higgs Mass and Tests Standard Model
March 2, 2012
The world's most precise measurement of the mass of the W boson, one of nature's elementary particles, has been achieved by scientists from the CDF and DZero collaborations at the Department of Energy's Fermi National Accelerator Laboratory. The new measurement is an important, independent constraint of the mass of the theorized Higgs boson.
