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

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

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

Columbia professors contributed to new research that seeks to understand an anomaly that has puzzled particle physics for ...

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

The KATRIN (Karlsruhe Tritium Neutrino) experiment has provided fresh insights into sterile neutrinos. Neutrinos ...

Baryons, composite particles made up of three quarks bound together via the so-called strong force, make up the most visible matter and have thus been the focus of numerous physics studies. Studying ...

An extensive search for a hypothetical particle has turned up empty. The sterile neutrino is a proposed subatomic particle that could even be a candidate for the mysterious dark matter, and although ...

Scientists have produced the firmest evidence yet of so-called sterile neutrinos, mysterious particles that pass through matter without interacting with it at all. The first hints these elusive ...

Physicists using near-absolute-zero detectors have reached unprecedented sensitivity in the hunt for light dark matter. A ...

Diana Parno’s head swam when she first stepped inside the enormous, metallic vessel of the experiment KATRIN. Within the house-sized, oblong structure, everything was symmetrical, clean and blindingly ...

The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.
