Scientists are closing in on identifying a new force of nature after observing the peculiar 'wobble' of a subatomic particle. The experts whizzed tiny muons, which are similar to electrons, through a ...

The Department of Energy’s Fermi National Accelerator Laboratory near Chicago. If accurate, it’s a sign that the theories forming the foundation of modern particle physics don’t tell the whole story.

For more than 10 years, scientists have known that charm mesons, subatomic particles that contain a quark and an antiquark, can travel as a mixture of their particle and antiparticle states, a ...

GENEVA – To cheers and standing ovations from scientists, the world’s biggest atom smasher claimed the discovery of a new subatomic particle Wednesday, calling it “consistent” with the long-sought ...

New measurements of a subatomic particle provide the strongest hint yet that the leading theory of quantum physics that explains our universe may be missing a fundamental element, scientists say. The ...

BEIJING - A group of international scientists working with the Beijing Spectrometer III (BES III) on Tuesday announced that they may have detected a new subatomic particle. The new finding, referred ...
