In a cavernous tunnel beneath the French–Swiss border, physicists have briefly recreated conditions that existed microseconds ...

Using the world's most powerful particle accelerator, CERN's Large Hadron Collider, scientists have discovered that the trillion-degree hot primordial "soup" that filled the cosmos for mere millionths ...

CERN's ALICE experiment has resolved the puzzle of deuteron formation, showing that most deuterons form via resonance-driven ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

Scientists analyzing data from heavy ion collisions at the Large Hadron Collider (LHC)—the world's most powerful particle ...

Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that ...

Every time two beams of particles collide inside an accelerator, the universe lets us in on a little secret. Sometimes it's a particle no one has ever seen. Other times, it's a fleeting glimpse of ...

A new particle detector has passed a crucial test that shows it is ready to detect the "ashes" left over from a unique primordial soup that filled the universe immediately after the Big Bang. The ...

Forget about turtles; for all practical purposes, it’s really particles all the way down. Consider the seemingly simple matter of their size, the very thing that makes them so alien. We’re typically ...

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 ...

In the alphabet-soup world of subatomic physics, only one letter was missing. The equations of quantum theory had indicated the existence of 17 pairs of basic “building blocks”—particles and ...
