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

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

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, ...
