Physics experiment suggests existence of new particle

The results of a high-profile Fermilab physics experiment involving a University of Michigan professor appear to confirm strange 20-year-old findings that poke holes in the standard model, suggesting the existence of a new elementary particle: a fourth flavor of neutrino.

Man, this one's go it all ! … symmetry broken ! ..

The new results go further to describe a violation of a fundamental symmetry of the universe asserting that particles of antimatter behave in the same way as their matter counterparts.

But wait, there's more !… a dark matter candidate ! …

The three known types of neutrino interact with matter primarily through the weak nuclear force, which makes them difficult to detect. It is hypothesized that this fourth flavor would not interact through the weak force, making it even harder to find.

"Physicists and astronomers are looking for sterile neutrinos because they could explain some or even all of the dark matter of the universe"

Very interesting. They conclude with a cautionary note that they need more data (which makes a lot of sense). This is great research. Good on them.
Have to keep track of this one.
