The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the ...

Subatomic particles are best described with fuzzy math. We don't know exactly where an electron is — but we know the odds that it's at a certain point in a general area that is ringed by a boundary.

Researchers at CERN have observed for the first time that matter and antimatter behave differently in decaying, heavy ...

Collapsing stars might act as cosmic laboratories for discovering hidden neutrino interactions. Neutrinos are among the most puzzling particles in the universe. Nearly massless and incredibly elusive, ...

Heavy-ion collisions involve the collision of positively charged nuclei of heavy elements at nearly the speed of light. These ...

About 100 trillion neutrinos pass through your body every second, according to the observatory. They are the lightest particles we know of that have mass, and are fundamental, meaning they are not ...

A subatomic particle called a kaon decays into other particles that leave distinct spirals in this bubble chamber image from the 1970s. CERN In the same decade, particle accelerators came to the fore.

Subatomic particles can be separated into two categories: fermions and bosons. The primary differences between the two are how they spin and how they interact with each other.

It’s the rarest particle decay ever discovered. Scientists have clinched the case for a special type of decay of subatomic particles called kaons. Further study of the rare decay could reveal a ...

The announcement comes amid a flurry of activity this week at CERN: Also Tuesday, the LHC’s underground ring of superconducting magnets that propel infinitesimal particles along a 27-kilomete… ...
