The Standard Model could make predictions up to exponentially high energies — 10^30 GeV or above. The high energy behavior of the hypercharge gauge coupling is likely poorly behaved.

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 ...

For decades, physicists sought the Higgs boson: the theorized “God particle” whose alter ego, a field pervading the entire universe, endows matter with mass. In 2012, scientists finally found ...

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

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

For normal double-beta decay, the half life — the time it takes for half the substance to decay — is 10 21 years, or 100 billion times longer than the age of the universe.

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 ...

Discovery of an elementary particle not predicted by the Standard Model of Particle Physics has been reported and confirmed. In the mid-1930s, ...
