Latest DØ experiment Stories

Lee Rannals for redOrbit.com - Your Universe Online Tevatron scientists have made a lackluster announcement before Wednesday's big event, by admitting they are still uncertain about the existence of the God particle. Just two days before the highly anticipated announcement of the latest Higgs-search results come out from the Large Hadron Collider in Europe, the U.S. Department of Energy’s Tevatron collider scientists failed to announce a finding first, but did present more evidence....

Scientists working at the US Tevatron particle collider near Batavia, Illinois on Wednesday said they have found the strongest evidence yet for the existence of the elusive “God particle.” They said their experiments mirror those from the Large Hadron Collider (LHC) in Europe that have narrowed the range where the Higgs boson particle could be hiding. The Higgs Boson is the missing link in the standard model of physics and is believed to be what gives objects mass, though scientists...

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. It also provides a rigorous test of the Standard Model that serves as the blueprint for our world, detailing the properties of the building blocks...

Data that hinted at the possible discovery of a new sub-atomic particle has been rejected after cross-checks failed to find support for the initial observation, according to a recent BBC News report. Researchers working on the CDF experiment at the US Tevatron "atom smasher" announced in May that they had detected exciting hints of a possible unanticipated particle. But in a separate experiment --called DZero -- cross-checks of the data lacked any good evidence of the findings. The DZero...

New constraints on the elusive Higgs particle are more stringent than ever before. Scientists of the CDF and DZero collider experiments at the U.S. Department of Energy's Fermilab revealed their latest Higgs search results Monday July 26 at the International Conference on High Energy Physics, held in Paris from July 22-28. Their results rule out a significant fraction of the allowed mass range established by earlier experiments.The Fermilab experiments now exclude a Higgs particle with a mass...

The Tevatron accelerator "atom smasher" may get three extra years of usage in order to continue its hunt for the elusive God particle. Physicists at the Tevatron -- based in Batavia, Illinois and operated by the Fermi National Accelerator Laboratory (Fermilab) -- are hoping to keep the accelerator operational until 2014, as they think the Higgs boson is within their grasp. The Higgs boson is a sub-atomic particle considered crucial to the current theory of particle physics. The Tevatron is...

Physicists have denied rumors that a U.S. atom smasher has detected the elusive Higgs boson.A spokesman for the lab that operates the Tevatron accelerator denied scientists had made a discovery there. The Tevatron, based at Fermilab in Illinois, is the U.S. rival to Europe's Large Hadron Collider (LHC).  An Italian particle physicist made the rumors public through a blog post. However, a spokesman for the Fermi National Accelerator Laboratory (Fermilab) told BBC News, "There is not...

According to a new study, there may be multiple versions of the elusive "God particle," or Higgs boson. The Higgs boson particle is the primary goal for the $10 billion Large Hadron Collider (LHC) experiment near Geneva. However, recent studies from the LHC's U.S. rival suggest physicists could be hunting for five particles, not one. The data points to new laws of physics beyond the current accepted theory, known as the Standard Model. The Higgs boson is the sub-atomic particles...

UC Riverside physicists involved in the international research; new result brings us closer to understanding the universe and its originsWhy is there matter in the universe and not antimatter, its opposite?Physicists at Fermi National Accelerator Laboratory, including John Ellison, a professor of physics at UC Riverside, have announced that they have found evidence for a significant violation of matter-antimatter symmetry in decays of B-mesons, which are exotic particles produced in high...

Physicists at Fermilab have discovered a clue as to why the world around us is composed of normal matter and not anti-matter. Today, anti-matter is rare, but it can be produced by atom smashers, in nuclear reactions, or by cosmic rays. However, physicists believe the Big Bang should have produced equal amounts of matter and its opposite. The DZero experiment at Fermilab in Illinois has now produced results that provide a clue as to what happened to all the anti-matter. Many researchers...
