That's physics beyond the standard model. I don't know if there are any string theory derived models which have that. But note the following points:
1) It's never happened in the 13.8 billion years of the universe's history since the electro-weak epoch.
2) L.H.C. won't do that, if it could then any higher energy collision could and they happen regularly on Earth - occasionally a cosmic ray comes along (at least daily) with the same energy as a cricket ball doing 60 miles an hour (LHC's protons have about the same energy as a flea). It hasn't ended the universe yet so LHC won't.
3) If it did happen the phase transition boundary would pass us at, or just under, the speed of light and all the physics that causes electrical impulses in our body would stop working. We wouldn't feel a thing.
So don't worry about it.
