Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest ...

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

With survey operations set to begin this fall, the Rubin control room at SLAC will serve as a key hub for training and remote observing support for the NSF–DOE Vera C. Rubin Observatory. All eyes are ...

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 ...

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 ...

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.

New results from the world’s most sensitive dark matter detector put the best-ever limits on particles called WIMPs, a leading candidate for what makes up our universe’s invisible mass. Figuring out ...

Nobel Laureate Peter Higgs died earlier this year. Twelve years ago this week, physicists discovered the particle that bears his name. When researchers at the Large Hadron Collider announced the ...

Electromagnetism and the weak nuclear force are two distinct fundamental forces. That wasn’t always the case. How many fundamental forces are there in our universe? For particle physicists, answering ...
