In the biggest result of its kind in more than ten years, physicists have made the most sensitive measurements yet in a decades-long hunt for a hypothetical and rare process involving the radioactive ...

The process: The study focuses on a radiation-induced process by which weakly bound matter can fall apart, the so-called electron-transfer-mediated decay (ETMD). Given predictions that it efficiently ...

Scientists have discovered an ultra-rare particle decay process, opening a new path to find physics beyond our understanding of how the building blocks of matter interact. Scientists at CERN have ...

Neutrinoless double-β decay is possible only if neutrinos have mass, a condition that has now been confirmed, thanks to the detection of neutrino oscillations. The race is therefore on to find ...

For the first time, researchers have directly observed an exotic type of radioactive decay called two-neutrino double electron capture. The decay, seen in xenon-124 atoms, happens so sparingly that it ...
