One thing to keep in mind is that the particle will likely only lose a 'tiny' fraction of its energy in a collision (the article mentions 2900 TeV for an atom of nitrogen) and it might not even cause a 'hard' collision. A collision will probably create a shower of particles which will carry away most of the energy.
