CERN team discovers heavy proton, advancing understanding of strong force LHCb spots ultra-brief, charm-rich baryon that ...

The world's largest particle accelerator has performed its first collisions, and its first beam acceleration. Progress on the giant experiment has been rapid in the four days since the Large Hadron ...

Estimating things that exist is generally easy, but when it comes to estimating things that do not exist, it's more difficult. This is something physicists from Poland and the UK are well aware of. To ...

The sPHENIX particle detector, the newest experiment at the Relativistic Heavy Ion Collider (RHIC) at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, has released its first ...

Scientists at the Large Hadron Collider (LHC) at CERN have successfully transmuted lead into gold — not by alchemy, but by smashing heavy ions together at nearly the speed of light. The process, ...

A snapshot of a computer simulation showing how energy density changes over time in the collision of a lead ion with a photon emitted by another lead ion. The world’s largest and most powerful ...

At the world’s most powerful colliders, physicists are finally catching sight of particles that almost never leave a trace, a “ghost” signal that has haunted theory for decades. The detection of these ...

Some of the most fundamental questions about our universe are also the most difficult to answer. Questions like what gives matter its mass, what is the invisible 96 percent of the universe made of, ...
