In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC ...

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 ...

Something is out there. As far as scientists know, just 15% of the matter in the universe is the ordinary kind we can see. The other 85%, called dark matter, remains beyond detection, invisibly ...

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: ...

The experiment's third and final result, based on the last three years of data, is in perfect agreement with previous results, further solidifying the experimental world average. Scientists working on ...

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 ...

The LHCb experiment at CERN has revealed a fundamental asymmetry in the behavior of particles called baryons. “The reason why it took longer to observe CP violation in baryons than in mesons is down ...

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 ...

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 ...
