As if atoms weren’t already mind-blowingly small, never mind subatomic particles, CERN researchers in the CMS Collaboration ...

A new measurement finds the universe's teensiest particles weigh no more than one-millionth the mass of an electron.

Our understanding of how the physical world works – from the tiniest subatomic particle to the largest galaxy cluster – has advanced rapidly in recent decades. As The Infinite Monkey Cage ...

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not ...

Physicists have shown that particles produced in collimated sprays called jets retain information about their origins in subatomic particle smashups.

Physicists studied proton interactions at the Large Hadron Collider to see if they could find quantum entanglement as a ...

At nearly 56.5 miles across, the FCC would be more than three times the LHC’s size while including eight surface laboratory ...

Physicists are finalizing plans for MATHUSLA, a powerful new addition to CERN's Large Hadron Collider that will detect ...

The AMoRE experimental collaboration in South Korea has reported not finding evidence of neutrinoless double beta decay after a two-year search, imposing stringent limits on this mysterious, ...

The KATRIN experiment in Germany nearly halved the maximum possible mass for neutrinos, setting it at 0.45 electron volts.

As part of an experiment called NA62, researchers detected and measured an ultra-rare form of decay for a subatomic particle ...
