LHC

Scientists know the Higgs boson interacts with extremely massive particles. Now, they’re starting to study how it interacts with lighter particles as well.

The ATLAS and CMS experiments at CERN have announced new results that show that the Higgs boson decays into two muons. US CMS — the United States contingent of the global CMS collaboration — played a crucial role in this result, contributing to the excellent performance of CMS detector.

On June 19, scientists at the CMS experiment at CERN’s Large Hadron Collider published their 1,000th paper. The monumental achievement reflects an incomparable contribution to humanity’s understanding of the universe — and it’s just the beginning.

From Lawrence Berkeley National Laboratory, June 17, 2020: While COVID-19 risks had led to a temporary halt in fabrication work on high-power superconducting magnets built by a collaboration of three national labs for an upgrade of the world’s largest particle collider at CERN in Europe, researchers at Berkeley Lab are still carrying out some project tasks. Fermilab scientist Giorgio Apollinari, head of the U.S.-based magnet effort for the HL-LHC, is quoted in this piece.

Scientists on Large Hadron Collider experiments can learn about subatomic matter by peering into the collisions and asking: What exactly is doing the colliding? When the answer to that question involves rarely seen, massive particles, it gives scientists a unique way to study the Higgs boson. They can study rare, one-in-a-trillion heavy-boson collisions happening inside the LHC.

In this imaginative film, Symmetry writer Sarah Charley depicts a short story in which a physicist is unable to cook what he wants with the ingredients he has. It’s not easy to get the grocery while sheltering in place, so he decides to use the physics at work in the Large Hadron Collider to get what he needs.
