Researchers at CERN have observed for the first time that matter and antimatter behave differently in decaying, heavy subatomic particles.

Neutrinos are elementary particles that are predicted to be massless by the standard model of particle physics, yet their observed oscillations suggest that they do in fact have a mass, which is ...

Calculating the electron's magnetic moment: State-dependent values emerge from Dirac equation by Cynthia Eller, California Institute of Technology ...

The CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed an unforeseen feature in the behaviour of top quarks that suggests that these heaviest of all elementary particles form a ...

An unforeseen feature in proton-proton collisions previously observed by the CMS experiment at CERN’s Large Hadron Collider (LHC) has now been confirmed by its sister experiment ATLAS. The result, ...

Researchers at ETH Zurich are combining their results with findings from teams in Germany and Australia. Beyond the Standard Model: The Quest for New Forces The Standard Model of particle physics very ...
