Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the ...

New results from the MicroBooNE experiment at Fermilab found no evidence of a hypothetical fourth flavor of neutrino ...

Two papers challenged the existence of theorized particles called sterile neutrinos that might account for mysteries like the ...

Neutrinos are tiny subatomic particles that barely interact with matter. They can pass through planets without stopping. The ...

The Standard Model of Particle Physics is the collection of discoveries and theories that describe the smallest units of matter and the interactions between energy and matter. According to this model, ...

For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Deep underground in southern China, there is a 20,000-ton tank of liquid that can detect neutrinos. Named JUNO, the ...
