A surprising and rare particle decay has left scientists puzzled as kaons, particles made up of quarks, are decaying in ways that defy current physics models. Could this anomaly indicate the existence ...

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 ...
