Since they are really obsessed with proving this particle exists, I can’t but wonder if that may taint their research a little.
Nah. Just because the Standard Model of Physics is based on the Higgs Boson ('God Particle') existing, and without it modern Physics collapses into a world of meaningless nothing-less, has no effect at all on their research or findings.
After all, these guys are 'scientists'(1).
(1) The only one of them I'd trust is Leon Lederman and he isn't over at CERN. He's living 'next door' to me in Batavia, IL, and 'semi retired' now (iirc).

Me too, we may be approaching the point of critical ass, the point at which anything posited to exist can be found if we spend enough money looking for it. There are many theories of reality and reality has been said to be the only illusion we all share. Some go so far as to say that anything, repeat anything, can be found if we assume its existence and look for it diligently enough. That idea seems to fit with my very limited exposure to string theory.
