If I've read this correctly, it seems the LHC will be colliding beams at 7 TeV each, producing a total collision energy of 14 TeV. The previous record was approximately 950 GeV at LEP/Tevatron producing a total collision energy of 1900 TeV. When the LHC starts colliding early next year (perhaps sooner), they want to use 3.5 TeV per beam. So does this mean physicists will be analysing this data for new discoveries, since collisions will have 3x more energy than any previous collision in a detector? Why is there such a rush to get to 7 TeV per beam? Is there some sort of physics that isn't predicted to happen until 14 TeV is reached? Do all the particles/events that happen at 14 TeV also happen at 2x3.5 TeV?
