The CMS collaboration has recently presented new results in searches for long-lived heavy neutral leptons (HNLs). Also known as "sterile neutrinos", HNLs are interesting hypothetical particles that could solve three major ...

It was an anomaly detected in the storm of a nuclear reactor so puzzling that physicists hoped it would shine a light on dark matter, one of the universe's greatest mysteries.

A new result from the MicroBooNE experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory probes the Standard Model—scientists' best theory of how the universe works. The model assumes there are ...

New scientific results confirm an anomaly seen in previous experiments, which may point to an as-yet-unconfirmed new elementary particle, the sterile neutrino, or indicate the need for a new interpretation of an aspect of ...

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.

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 ...

There are many questions surrounding the elementary particle neutrino, in particular regarding its mass. Physicists are also interested in whether besides the 'classic' neutrinos there are variants such as the so-called sterile ...

About eighty-five percent of the matter in the cosmos emits neither light nor any other known kind of radiation as far as is known, and hence is called dark matter. One of its other notable qualities is that it only interacts ...

The standard model of particle physics only accounts for 20% of matter in the universe. Physicists have theorized that the remaining 80% is made up by so-called dark matter, which consists of particles that do not emit, absorb ...
