Scientists at Berkeley Lab will be sifting through loads of new data expected from the latest experimental run at CERN’s Large Hadron Collider.
Scientists at the Large Hadron Collider at CERN, the European research facility, start recording data from the highest-energy particle collisions ever achieved on Earth.
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.
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.
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
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.

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.
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.
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.
