Long-lived particles get their moment
Scientists on experiments at the LHC are redesigning their methods and building supplemental detectors to look for new particles that might be evading them.
A new view of the Higgs boson
Scientists know the Higgs boson interacts with extremely massive particles. Now, they’re starting to study how it interacts with lighter particles as well.
Behind the scenes of the CMS experiment’s 1,000th paper
What does it take to publish a scientific analysis in one of the world’s largest experiments? A huge amount of meticulous work and scrutiny goes into each paper published by CMS, a collaboration of about 3,000 scientists.
The invisible Higgs bosons
Experimentalists and theorists search for Higgs bosons escaping as dark matter.
The large boson-boson collider
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.
The Large Kitchen Collider
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.
Ten years of LHC physics, in numbers
In 2010, the Large Hadron Collider research program jumped into full swing as scientists started collecting physics data from particle collisions in the LHC for the first time. How has this gigantic, global scientific effort affected the world? Symmetry pulled together a few numbers to find out.
Scientists search for origin of proton mass
Only 1% of the mass of the proton comes from the Higgs field. ALICE scientists examine a process that could help explain the rest.
Accounting for the Higgs
Only a fraction of collision events that look like they produce a Higgs boson actually produce a Higgs boson. Luckily, it doesn’t matter.
