Berkeley Lab Researchers Part of an International Hunt

In our universe there are particle accelerators 40 million times more powerful than the Large Hadron Collider (LHC) at CERN. Scientists don’t know what these cosmic accelerators are or where they are located, but new results being reported from “IceCube,” the neutrino observatory buried at the South Pole, may show the way. These new results should also erase any doubts as to IceCube’s ability to deliver on its promise.

“The IceCube Collaboration has announced the observation of 28 extremely high energy events that constitute the first solid evidence for astrophysical neutrinos from outside our solar system,” says Spencer Klein, a senior scientist with Lawrence Berkeley National Laboratory (Berkeley Lab) and a long-time member of the IceCube Collaboration. “These 28 events include two of the highest energy neutrinos ever reported, which have been named Bert and Ernie.” (more…)

Nobel in Physics: A long time in the making

Nearly 50 years of experiments and billions of dollars in equipment followed the prediction of the Higgs mechanism by theoretical physicists in 1964. Ulrich Heintz and Meenakshi Narain, two of the particle physicists at Brown University who worked on experiments at Fermilab and at CERN, note that the successful search for the Higgs was caried on by thousands of researchers.

The Nobel Prize awarded today to Francois Englert and Peter Higgs was a long time in the making. The Higgs mechanism was invented almost 50 years ago, and ever since the standard model emerged as the explanation of everything in particle physics that we have observed so far. The search for the Higgs boson was a quest that heated up for particle physics experimenters with every new facility that came online. Some of us (Heintz, Narain) looked for it in their thesis experiment at the Cornell Electron Storage Ring in the 1980s. Then the search moved to European Organization for Nuclear Research (CERN) to the Large Electron Positron Collider, and back again to the Tevatron at Fermilab near Chicago, where we (Cutts, Heintz, Landsberg, Narain) were part of the discovery of the top quark in 1995 with the D-Zero experiment.

UCLA physicists played prominent role in Nobel Prize-winning Higgs boson research

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…)

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…)

Homing in on Higgs: Michigan Researchers Predict Summer Discovery

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…)

Go Ask ALICE: Learning About the Big Bang

Nearly 14 billion years ago, the universe began with a bang — a big one.

Scientists believe that the universe and everything within it began as an extremely hot, dense “soup” that eventually gave rise to galaxies, stars, planets and life and that continues to expand to this day.

Now scientists around the world are pushing back the frontiers of our understanding about the moment the universe was born using the Large Hadron Collider (LHC), a giant particle accelerator at CERN (the European Organization for Nuclear Research) near Geneva, Switzerland. (more…)

Time Machine Built in Europe, Russian Scientists Say

Russian physicists seriously believe that the Large Hadron Collider can be used for time travel. However, it will only happen when it starts working at full capacity and stops breaking down. If earlier time travel was considered science fiction, now it suddenly turned into the favorite pet project of theoretical physicists. Renowned physicist Kip Thorne of the California Institute of Technology once said in one of his lectures:
