So what type of dark matter particle was this particular experiment trying to detect?

[Boogieman]

Well, they don’t really know what kind of particles this theoretical “dark matter” would be, since they have never been able to detect or observe any of it. They have some guesses, but that is all they are at this point.

So what type of dark matter particle was this particular experiment trying to detect?

They are trying to detect something that is completely unknown and has eluded all previous efforts to find.

If you were to find it?

You could name it "Moonman62"
