At Fermilab, US physicists are refining their measurements of this subatomic particle—which has major implications for the Standard Model.

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their understanding of physics ...

Instead of bosons, what came up was a signal from a type of fermion—a particle whose spin has only odd half-integer values such as 1/2 or 3/2. The particular fermion they found is a top quark ...

A subatomic particle called the muon caused waves when its experimental behaviour didn't align with a prediction based on the standard model. A new calculation might resolve the discrepancy ...

DURHAM, N.C. -- One of the tiniest building blocks of the universe has a weigh-in problem, and Ashutosh Kotwal is determined to get to the bottom of it.. For nearly 30 years, the Duke physicist has ...

In a landmark experiment, scientists have found fresh evidence that a subatomic particle is disobeying one of science’s most watertight theories, the Standard Model of particle physics. The gap ...

But axions were pushed aside as the WIMPs hypothesis gained more steam. Back-of-the-envelope calculations showed that the ...

As part of an experiment called NA62, researchers detected and measured an ultra-rare form of decay for a subatomic particle called a kaon. This is one of the rarest interactions in particle ...

When Israeli aircraft recently struck a uranium-enrichment complex in the nation, Iran could have been days away from ...

A boson is a subatomic particle with an angular momentum (spin) that has integer values. Photons are bosons, as are gluons , which act as force carriers in the nucleus.
