Two large collaborations of scientists working at the Large Hadron Collider in Switzerland made worldwide news in July 2012 when they announced independent observations of the elusive Higgs boson particle — a discovery hailed as one of the greatest scientific accomplishments of recent decades.
This so-called “God particle” was first postulated some 50 years ago as a crucial element of the modern theory of the forces of nature — it is, physicists say, what gives everything in the universe mass — and it had been the subject of worldwide searches ever since. (more…)
The long-sought Higgs boson—the particle that endows all elementary particles in the universe with mass—was elusive no longer when scientists at the CERN physics laboratory in Switzerland, discovered it last summer.
The July 4, 2012 announcement of the discovery appealed to both the general public and the media: Fifty-five media organizations and more than one billion television viewers made it an event that couldn’t be missed. Time even dubbed the Higgs boson “Particle of the Year.” (more…)
Berkeley Lab scientists, major contributors to the ATLAS experiment at the Large Hadron Collider, explain what the excitement is about
CERN, the European Organization for Nuclear Research headquartered in Geneva, Switzerland, will hold a seminar early in the morning on July 4 to announce the latest results from ATLAS and CMS, two major experiments at the Large Hadron Collider (LHC) that are searching for the Higgs boson. Both experimental teams are working down to the wire to finish analyzing their data, and to determine exactly what can be said about what they’ve found.
“We do not yet know what will be shown on July 4th,” says Ian Hinchliffe, a theoretical physicist in the Physics Division at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), who heads the Lab’s participation in the ATLAS experiment. “I have seen many conjectures on the blogs about what will be shown: these are idle speculation. Things are moving very fast this week, and it’s an exciting time at CERN. Many years of hard work are coming to fruition.” (more…)
ANN ARBOR, Mich.— Whether the Higgs boson exists could be settled by the end of summer, say University of Michigan physicists involved in the search for the missing piece of particle physics’ Standard Model.
“We’re zooming in,” said Jianming Qian, physics professor in the College of Literature, Science & the Arts. “We are increasing the data set and improving our search algorithms. With certain luck, we may be able to discover it this summer, but it depends on nature.”
Qian is one of the 28 U-M researchers involved in experiments at CERN’s Large Hadron Collider (LHC) in Switzerland. He’ll spend most of his time through August in Geneva, where more than 1,000 scientists from around the world have been looking for Higgs since the collider turned on about four years ago. (more…)
A new atlas and catalog of the entire infrared sky with more than a half-billion stars, galaxies and other objects captured by NASA’s Wide-field Infrared Survey Explorer (WISE) mission was unveiled by NASA Wednesday.
“Today WISE delivers the fruit of 14 years of effort to the astronomical community,” said Edward L. (Ned) Wright, a UCLA professor of physics and astronomy and the mission’s principal investigator, who began working on the mission in 1998. (more…)
