The CMS Collaboration has shown, for the first time, that machine learning can be used to fully reconstruct particle ...

At CERN’s Large Hadron Collider on the edge of Geneva, scientists have reported a surprising twist in the behavior of matter.

At the heart of every atomic nucleus, the strong interaction quietly dictates the structure of matter, yet for decades one of its simplest products refused to fit the script. The way fragile “light ...

A particle collision reconstructed using the new CMS machine-learning-based particle-flow (MLPF) algorithm. The HFEM and HFHAD signals come from the ...

Data from past proton-electron collisions provide strong evidence of entanglement among the proton's sea of quarks (spheres) and gluons (squiggles), which may play an important role in their ...

Black holes remain one of the most enigmatic objects in the cosmos, offering profound insights into the nature of gravity and spacetime. Research on particle collisions in the intense gravitational ...

A new and powerful particle detector just passed a critical test in its goal to decipher the ingredients of the early universe. The sPHENIX detector is the newest experiment at Brookhaven National ...

A black hole is more than just a region of space where nothing escapes. It can also become a powerful cosmic engine. When matter spirals inward, falling into its grasp, the black hole doesn't just ...

Physicists from the ATLAS collaboration at the European Organization for Nuclear Research — including members of Penn’s ATLAS group — have been awarded the 2025 Breakthrough Prize in fundamental ...

Scientists trying to replicate conditions that existed in the first microsecond after the Big Bang have discovered that gold ions ramming each other at nearly the speed of light produce a surprisingly ...

The sPHENIX detector is the newest experiment at Brookhaven National Laboratory’s Relativistic Heavy Ion Collider (RHIC) and is designed to precisely measure products of high-speed particle collisions ...
