A sterile neutrino is so quiet that it can only be detected by the silence it leaves behind.
This anomaly has been observed before. Now it has been rediscovered during the Baksan Experiment on Sterile Transitions (BEST).
If it is confirmed that it was indeed a sterile neutrino, it could become a potential candidate for the source of dark matter in the Universe.
On the other hand, the anomalies can be explained by the presence of a problem in the models used to describe the behavior of neutrinos.
“The results are very exciting!They confirm that the previous anomaly was not an error. On the other hand, everything is not completely obvious. There are now conflicting results about sterile neutrinos. For example, according to one of them, fundamental nuclear and atomic physics are interpreted incorrectly,” says Los Alamos National Laboratory physicist Steve Elliott.
Neutrinos are among the most commonparticles in the Universe, but they are difficult to catch. They have almost no mass, no electric charge: they can only be tracked by the weak nuclear force.
If the anomaly that physicists have observed is indeed a sterile neutrino, then scientists would finally have evidence that there are many particles, but they only affect gravity.
