Some cosmic rays come from the sun, some from elsewhere in our Milky Way, and others, called extragalactic cosmic rays, trace ...

A subatomic particle long predicted by theorists has finally been observed, ending a decades-long wait in physics. Named Ξcc+ ...

Scientists have used CERN's Large Hadron Collider (LHC) to uncover what they say is an entirely new type of particle, dubbed ...

WASHINGTON (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their ...

The new baryon “Xi-cc-plus” decays into other particles almost instantly, but its existence could paint a clearer picture on ...

NPR's Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab's most precise measurements of the muon particle's magnetic wobble. It's ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...
