New results from the MicroBooNE experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory deal a blow to a theoretical particle known as the sterile neutrino. There is no such thing.

For decades, physicists have theorized that the current best theory describing particle physics—the "Standard Model"—was not sufficient to explain the way the universe works. In the search for physics beyond the Standard ...

Experiments have spotted anomalies hinting at a new type of neutrino, one that would go beyond the standard model of particle physics and perhaps open a portal to the dark sector. But no one has ever directly observed this ...

Neutrinos are tricky beasts. Alone among known fundamental particles, they suffer from an identity crisis—if it were possible to put them on a weighing scale, you would unpredictably measure one of three possible masses. ...
