It would be a spectacular triumph for CERN to produce a particle that might constitute the dark matter (like the WIMP you suggest). While possible, I consider this outcome to be unlikely.https://twitter.com/malnadi/status/1132847678663143430 …
I would add that this is given the experimental results over the past few years, which have heavily constrained the WIMP parameter space. Initially, they were a good guess but nature just didn't say yes.

Yet! Or Ever?

Yet. But the wimps parameter space is as I mentioned heavily heavily constrained. You can see in this plot that the cross section is getting "pushed" lower and lower at higher mass. This is why people are now exploring the avenue of "light" dark matterpic.twitter.com/n1EaZ2Rc2c

But these constraints rely on interactions of Baryonic matter as we know it? Isn't it true that the only known interactions DM experiences is gravitation? So the constraints are imposed on interactions that may not even happen? Sorry for the rookie questions. I am a rookie.

No problem, and it’s a great question. The heuristic that they only act gravitationally doesn’t exclude them interacting weakly with other forces. WIMPS themselves for example are assumed to be such particles.
