U.S. Scientists Celebrate the Restart of the Large Hadron Collider

With the collider back in action, the more than 1,700 U.S. scientists who work on LHC experiments are prepared to join thousands of their international colleagues to study the highest-energy particle collisions ever achieved in the laboratory.

What to Expect Next from the World’s Largest Particle Accelerator

Berkeley Lab researchers, Beate Heinemann and Peter Jacobs were on a recent panel of scientists that discussed the scientific implications of this new and improved accelerator.

Latest from ATLAS: Higgs Boson Behaves Just the Way it Should

At a CERN seminar November 26th, Aliaksandr (Sasha) Pranko of the Physics Division at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) presented key direct evidence that the “Higgs-like” particle discovered at CERN last year does what a Higgs is supposed to do: it couples not only to other bosons but to

Berkeley Lab’s Prominent Role in the Higgs Discovery

The Nobel Prize in Physics to François Englert and Peter Higgs cites confirmation of their work by the ATLAS and CMS experiments, in what Physics Division Director Natalie Roe calls “a powerful testament to human imagination, innovation, perseverance and international cooperation.” Berkeley Lab provides one of the largest U.S. contingents to ATLAS, led by Ian Hinchliffe. Berkeley Lab’s Physics, Accelerator, and Engineering Divisions have made and continue to make vital contributions to the LHC.

Understanding What’s Up With the Higgs Boson

On July 4 CERN released the latest results in the search for the Higgs boson. Members of the ATLAS and CMS experiments who are leading the search announced the observation of a new particle “consistent with the Higgs” at a very high level of confidence. Berkeley Lab has a large contingent of physicists in the ATLAS collaboration, some in key posts. They explain what’s involved in the Higgs search and what happens next, now that the news has broken.

A Flow of Heavy-Ion Results from the LHC

CERN’s Large Hadron Collider collides protons most of the year but switches to massive lead nuclei for a month. Collisions of these heavy ions reproduce the quark-gluon plasma that filled the universe millionths of a second after the big bang. Much of the program for quark-gluon plasma studies is shaped by theoretical and experimental contributions from Berkeley Lab’s Nuclear Science Division, as shown by results from ALICE and other experiments during the LHC’s first lead-lead run just concluded.

Large Hadron Collider Pauses Protons; Looks Ahead to Lead

The Large Hadron Collider has completed many successful months of colliding protons (hydrogen ions) at record-breaking energies and now begins four weeks of colliding much more massive lead ions, giving access to different physical phenomena. Berkeley Lab hosts U.S. participation in the ALICE experiment, designed specifically to study the heavy-ion collisions that give rise to a unique phase of matter, the quark-gluon plasma. Berkeley Lab is also a major participant in the ATLAS experiment, one of the other LHC experiments that will study lead-lead collisions.

Bay Area’s Berkeley Lab Plays a Major Role as the Large Hadron Collider Enters the Realm of New Physics

Beams of protons were brought together in the first focused collisions on Tuesday, March 30, at CERN’s Large Hadron Collider. The world’s record collisions open a new realm of high-energy physics.

Beams are Back in the Large Hadron Collider

After more than a year of repairs, the Large Hadron Collider located at the CERN laboratory near Geneva, Switzerland is back on track to create high-energy particle collisions that may yield extraordinary insights into the nature of the physical universe.
