For the first time, scientists observe a new and rare decay mode where oxygen-13 breaks into three helium nuclei and a proton following beta decay. Scientists have previously observed interesting ...

Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing investigation of CP symmetry. The anomalies could be ...
