The NA62 Collaboration has dramatically reduced the uncertainty in its measurement of an extremely rare particle decay, in ...

FAYETTEVILLE — Gregory Christopher Decay, convicted in two 2007 murders, has started his state appeals process aimed at getting his two death sentences overturned. Decay gunned down Kevin Barkley ...

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 ...

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 ...

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 ...
