The S-matrix can be written as the sum of the Feynman diagrams, divided by a factor of 1/sqrt[E] for each particle, where E is the particle's energy.
Does this mean at large energies, the probability amplitude to scatter is unlikely?
But how can such a statement be made when no physics is involved? There is no mention of the type of interactions, but it doesn't seem to matter: 1/sqrt[E] factor (for each external line) will make the likely-hood of scattering at high energies smaller than at a low energies.
