Others believe that fields may be made of something even more fundamental — tiny vibrating strings — but testing string theory has been problematic. “We all agree that there has to be something beyond ...

String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

The discovery of the Higgs boson hasn’t led to an explosion of new physics as many predicted. Now, some scientists think that hidden physics may be hiding beyond LHC’s view.

Scientists have long sought evidence to refute string theory, but a new test seeks to disprove key aspects with help from the ...

While the electromagnetic, weak, and strong forces are described by the Standard Model of particle physics, gravity remains an outlier—resisting efforts to be fully explained by quantum theory.

These wholly unexpected findings place the old standard model in new light. Its extension into supersymmetry is all but dead; the Higgs idea—central to the model—may have to be replaced by an ...

The new measurement from LHCb has found differences between baryons and antibaryons, which are made of three quarks and three ...

What is quantum physics? Put simply, it’s the physics that explains how everything works: the best description we have of the nature of the particles that make up matter and the forces with which they ...

For many years, scientists have been puzzling over whether certain discrepancies between theory and experiment point to "new physics" beyond the Standard Model, or whether they are simply ...

In theory, the universe should have been born with equal amounts of matter and antimatter. Yet all the visible structures we see today – including stars, galaxies, planets and people – are made almost ...

Because this interaction is sensitive to Standard Model deviations, it’s identified as one of the prime targets for finding new physics. Today, the KOTO experiment in Japan is searching for a ...
