Does the W boson break the Standard Model? Depends on how you measure it.
found a boson mass of 80,360 ±16 MeV, 10 MeV lower and 16% more precise than the previous estimate out of ATLAS, according to a“This updated result from ATLAS provides a stringent test, and confirms the consistency of our theoretical understanding of electroweak interactions,” Andreas Hoecker, a spokesperson for the ATLAS experiment, said in themeasured the boson’s mass to be 80,433 ± 9 MeV, based on collisions done at the Fermilab’s Tevatron accelerator in Illinois, also in 2011.
For perspective, the CDF Collaboration’s estimated boson mass is about 80 times the mass of a proton.“Since the ATLAS experiment’s document describes a ‘reanalysis’ of the same data that ATLAS already released in 2017, the fact that ATLAS obtains a similar value as before is to be expected,” said Ashutosh Kotwal, a physicist at Duke University and a member of the CDF Collaboration, in an email to Gizmodo. “The reanalysis uses essentially the same technique as the previous publication.
“The CDF measurement continues to be the world’s most precise measurement of the W boson mass,” Kotwal added., came up with very different numbers for the mass of this fundamental particle. Neither team has identified anything amiss with their approaches. “We’ve spent the last year showing the results all over the world, and there have been no substantive concerns found about the methods or the cross checks,” said David Toback, a physicist at Texas A&M University and a spokesperson for the CDF Collaboration, in an email to Gizmodo. “A combination of the collaborations from around the world has been convened to see if they could understand the differences, and they have also not come up with an explanation for the differences.
