Signals recorded by components of the sPHENIX calorimeter, which measures the energy of particles streaming from collisions, during a full-energy (200-billion-electron-volt) gold-gold collision at ...

The problem comes when working with complicated collisions that cause loops (particles emitting and reabsorbing other particles in the middle of the collision process).

Discover the fascinating world of particle physics — the most fundamental building blocks of the universe and the forces that connect them.

The first data from proton–lead collisions at the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at CERN include a “ridge” structure in correlations between newly generated ...

Recent advancements in particle acceleration technology have led to the discovery of a new method that promises to ...

Extreme collisions between neutron stars could create exotic particles beyond the standard model, including axions, the hypothetical particle that comprises dark matter.

Proton collisions probe the final frontier of the standard model of particle physics The nuclear forces that act on short-lived subatomic particles have been hard to study.

The hunt for new physics is back on. The world’s most powerful machine for smashing high-energy particles together, the Large Hadron Collider (LHC), has fired up after a shutdown of more than ...

Scientists at the Large Hadron Collider announced March 30 that the LHC had collided particles to 7 trillion electron-volts, the highest energy ever achieved in such a device.

Smash-ups between dead neutron stars create and trap ultrahot ghost particles called neutrinos, new simulations have shown. The discovery could help us better understand how elements like gold are ...
