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 ...

Neutrinos don’t seem to get their mass in the same way as other particles in the Standard Model. In 1998, researchers made a discovery that challenged their understanding of particle physics and ...

The average banana produces a particle of antimatter roughly once every 75 minutes. US-based scientists and students working on research and experiments with the Large Hadron Collider contribute to a ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed. In 1980, Hamish Robertson was a ...

Scientists worried Higgs pairs would be too rare for LHC experiments to find. But by using machine learning, they now are getting tantalizingly close. In 2011, physicist Javier Duarte and his friends ...

Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning—but many researchers are not giving up on it yet. The Standard Model of particle physics is ...

Scientists around the world are testing ways to further boost the power of particle accelerators while drastically shrinking their size. At least when it comes to particle accelerators, bigger is ...

Physics may seem like its own world, but different sectors using machine learning are all part of the same universe. In 2017, Savannah Thais attended the NeurIPS machine-learning conference in Long ...

Our best model of particle physics explains only about 5 percent of the universe. The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and ...

From lightning to the death of electrons, the highest-energy form of light is everywhere. Gamma rays are the most energetic type of light, packing a punch strong enough to pierce through metal or ...

The 2013 documentary Particle Fever follows physicists from the start-up of the LHC through the discovery of the Higgs boson. Where are those physicists now? Physicist Monica Dunford remembers when ...
