It pretty much can't, since black holes are formed when large masses condense into such a small point in space-time that it collapses into a singularity. You're not going to get that by firing hydrogen ions at one another at 80% the speed of light.

Don't anybody get their hopes up that this will result in an answer to the Grand Unifying Theory. To even begin to test that would require a collision of energy in an order of magnitude so high, you'd need a super-collider the diameter of Pluto's orbit to pull it off.

Worst case scenario - they don't find anything useful in the new band of GeV they can now test in (very unlikely).
Best case scenario - they discover the Higgs Boson particle, or some other millisecond particle that turns the world of physics on its head.
