In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest scales. Photons, the fundamental particles of the electromagnetic field that ...

In addition to revealing characteristics of mysterious particles called neutrinos, the massive DUNE experiment could help astronomers find a supernova right as it begins. At this very moment, ...

A team of young scientists paused their new physics searches to develop an innovative machine-learning tool, which is now helping them narrow in on a rare and messy decay of the Higgs boson. Physicist ...

Scientists on the ATLAS experiment explored the polarization of W bosons to test the Higgs mechanism and gain a deeper understanding of the first moments after the Big Bang. After the Big Bang, the ...

Astronomers use brokers to identify which signals to pursue in an endless stream of alerts. Looking up at the stars at night, it may not be obvious that the universe is constantly changing. But it is: ...

A large and unexpected excess of top quark pairs has the physics community excited, but the interpretation is still up for debate. In 1995, Alexander Grohsjean cut out a story from the local German ...

Documenting the work of building the world’s largest neutrino experiment presents photographers with a unique set of challenges. Discussing her decades-spanning career, photographer Annie Leibovitz ...

Writer Chetna Krishna follows CERN’s “coolest” transport, a test of a system to ship stored antimatter across the continent. I reach CERN’s Antimatter Factory at 8 a.m. sharp. I’m here at the ...

Physicists in the United States support the development of an off-shore Higgs Factory. In 1964, the same year the Beatles rocked their way into the hearts of Americans on The Ed Sullivan Show, British ...

The Planck scale sets the universe’s minimum limit, beyond which the laws of physics break. In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws.
