March 7, 2012breaking: Tevatron experiments see possible signs of the Higgs boson in favored regionTevatron physicists told attendees of the Rencontres de Moriond conference this morning that they had found excesses in their data suggestive of a Higgs with a mass between 115-135 gigaelectronvolts. A few months ago, LHC physicists announced similar bumps indicating a Higgs with a mass of between 124-126 GeV.

March 2, 2012breaking: Fermilab's DZero experiment weighs in on W boson massThe DZero experiment at Fermilab's Tevatron collider made public today its most precise measurement of the mass of the W boson. Knowing the mass of this force-carrying elementary particle confirms the Standard Model of particle physics and puts constraints on the mass of the Higgs boson.

February 23, 2012breaking: World's best measurement of W boson mass tests Standard Model, Higgs boson limitsToday, scientists from the CDF collaboration have unveiled the world's most precise measurement of the W boson mass, based on data gathered at the Tevatron accelerator. The precision of this measurement surpasses all previous measurements combined and restricts the space in which the Higgs particle should reside according to the Standard Model, the theoretical framework that describes all known subatomic particles and forces.

February 1, 2012feature: The Tevatron's proud legacyJust after 2:30 p.m. on Sept. 30, Fermilab accelerator pioneer Helen Edwards prepared to stop the circulation of subatomic particles in the Tevatron collider for the last time. She was a fitting choice; Edwards and her husband, Don, had led the Tevatron start-up nearly three decades earlier. Now she would lay the massive collider to rest.

September 29, 2011breaking: Tevatron shutdown eveOn the eve of the shutdown of Fermilab's Tevatron, collaborators from the CDF and DZero experiments are expressing their gratitude for all the hard work and dedication that made 26 years of capturing billions of proton and antiproton collisions possible. In these final hours of operations, both collaborations are making the pen mightier than the proton by writing notes of thanks and appreciation.

July 22, 2011breaking: Higgs buzz at summer physics conferencePhysicists could be on their way to discovering the Higgs boson, if it exists, by next year. Scientists in two experiments at the Large Hadron Collider pleasantly surprised attendees at the European Physical Society conference this afternoon by both showing small hints of what could be the prized particle in the same area. “This is what we expect to find on the road to the Higgs,” said Gigi Rolandi, physics coordinator for the CMS experiment.

July 22, 2011breaking: How to find the Higgs particle; first Higgs search results from LHC and TevatronEditor's note: story updated at noon CDT on July 22: The LHC experiments reported at the EPS meeting a tantalizing excess of Higgs-like events, short of claiming a discovery, but very intriguing nevertheless. See the Higgs search at the LHC section further below for more information on these results.

July 21, 2011breaking: Wealth of particle physics data yields numerous results for EPS conferenceFermilab’s Tevatron particle collider is nearing the end of its lifetime, but results from its two collider experiments are nowhere close to dwindling. Members of the CDF and DZero collaborations at Fermilab will present a record number of results at this month’s European Physical Society conference on High-Energy Physics, which begins on July 21 in Grenoble, France.

June 10, 2011breaking: Fermilab's DZero weighs in on an unexpected CDF resultTwo months ago, CDF scientists reported an unexpected excess of proton-antiproton collisions that produce a W boson accompanied by two jets of particles. One possible explanation for the excess could be the existence of a new, unanticipated particle. Now the DZero collaboration has finished an independent analysis that tests the CDF result.
