Neutrinos are elementary particles that are predicted to be massless by the standard model of particle physics, yet their ...

The rare particle decay provides a great opportunity to test models of new physics, de Mattia said. "These decays are ideal processes in which to search for signs of new physical phenomena such as ...

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

LHC Scientists Spot Mystery Particle So Strange It Could Threaten Standard Model Published Nov 05, 2018 at 9:26 AM EST Updated Nov 05, 2018 at 9:28 AM EST An image of the Large Hadron Collider on ...

Discovered in 1983, the W boson plays an important role in the standard model (SN: 2/5/83). The particle comes in two varieties, with either positive or negative electric charge.

One fundamental building block in the Standard Model is the muon, a particle similar to an electron but 200 times more massive. The muon has a long history of revolutionising particle physics ...
