The Future Circular Collider (FCC) study develops options for potential high-energy frontier circular colliders at CERN for the post-LHC era. Among other things, it plans to look for dark matter particles, which account for approximately 25% of the energy in the observable universe. Though no experiment at colliders can probe the full range of dark matter (DM) masses allowed by astrophysical observations, there is a very broad class of models for weakly interacting massive particles (WIMPs) in the GeV – tens of TeV mass scale, and which could be in the range of the FCC.
Wild guess: they hacked the maths of those models/choose the models in order to fit the energy range of this new collider ? Ask Sabine H., need a BS meter evaluation... :)
You are in luck, this is exactly the sort of questions that accelerator designers like to answer. You can find the answers on the first 70 pages in volume 1 of the FCC feasibility report: https://cds.cern.ch/record/2928193 just the first
I think the money would be better spent on gravitational wave detectors as they might detect data about the true nature of black holes and help us develop a theory of quantum gravity or at least rule some out.
These experiments afaik don't require particle accelerators and are a different field of science, one of the largest of these detectors is the LIGO observatory overseen by Caltech
I know. That is why I think the money that would be spent on a new particle accelerator should be spent on new more sensitive gravitational wave detectors.
just one more accelerator bro. just one slightly larger accelerator than the one we just got online. we can revolutinize physics with just one more accelerator bro. Just give me 20 billion euros bro and we'll solve physics I promise br

There is a list of similar observatories in this document

Almost all accelerators built at CERN are still active and are a chain of pre-accelerator for LHC now:
