(Phys.org) —Researchers working at the Large Hadron Collider (LHC) have observed for the first time evidence of D-mesons oscillating between matter and antimatter. They describe their work, observations and the degree of ...
(Phys.org) -- Recently analyzed data from the BaBar experiment may suggest possible flaws in the Standard Model of particle physics, the reigning description of how the universe works on subatomic scales. The data from BaBar, ...
