It's like going to a doctor when you're sick.... you pay $$$ and then he gives you a piece of paper and you run off to the drug store/pharmacist to pay more $$ for 'drugs' that are supposed to make you better.
He has no idea what's really wrong (biologically atomic) with you except that certain $$$ drugs work with certain sicknesses. On the drug box there's a list of 'known' side effects.
Summary... plenty of $$$ to find the effects of something that they might have created, and does not really exist naturally in nature - this is a collider we're talking about
Not that this is a bad thing, but I'm always weary of 'scientists' who make claims (their reputations, and funding are on the line) - The test of time is good. ;)
We're still yet to see the electron, we understand 'some' of it's effects, but until we can pin point it physically we're have not completed the picture... there goes the cat.
