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

Neutrinos, the mysterious and nearly massless particles that barely interact with anything, are revealing new secrets through the KATRIN experiment. Using tritium decay and advanced spectrometry, ...

New data establish an upper limit of 0.45 eV/c2 (equivalent to 8 x 10-37 kilograms) for the neutrino mass. KATRIN measures neutrino mass in the laboratory using a model-independent method.

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 ...

In just the first 259 days of data collection, KATRIN, a beta-decay-based detector in Germany, has set the smallest upper ...

Quarks are the reason protons have a positive charge. Each quark has a fraction of an electric charge. A proton has two up ...

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

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

More than 13,500 scientists who have worked on experiments at the Large Hadron Collider (LHC), based in Geneva, Switzerland, have been awarded the ...

Researchers at the CMS collaboration at CERN have reported the discovery of the smallest hadron in existence, the toponium.

The Breakthrough Prize Foundation, established by Silicon Valley luminaries including the tech icons behind Google and ...

The Breakthrough Prize Foundation today announced the winners of the 2025 Breakthrough Prizes, honoring scientists driving ...
