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 ...

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

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 ...

Neutrinos are among the most enigmatic particles in the universe. They are omnipresent yet interact extremely rarely with ...

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.

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, ...

A new study in Monthly Notices of the Royal Astronomical Society by researchers including István Szapudi of the University of ...

Physicist Richard Lieu first explored the idea that gravity could exist without mass—now he’s got a new cosmological model ...
