    9 As typical values of four-momentum transfer squared, |t|, are smaller than 10 GeV^2^ in elastic (anti)proton-proton collisions, the influence of the weak force is negligible. Therefore, only the electromagnetic (Coulomb) and strong (hadronic) interactions are relevant for the elastic scattering. Their description can be split into the following elements:

Therefore, only the electromagnetic (Coulomb) and strong (hadronic) interactions are relevant for the elastic scattering. Their effects can be categorised in the following three groups.

     11* Effects due to '''strong interaction alone''' (in terms of Feynman diagrams, these would correspond to QCD diagrams only). For more details see [[HadronicModels|models of hadronic (strong) interaction]].
     12* Effects due to '''electromagnetic interaction alone''' (these would be QED diagrams only). For more details see [[CoulombInteraction|description of Coulomb (electromagnetic) interaction]].
     13* Effects of the '''interference between the strong and electromagnetic interactions''' (diagrams containing both QED and QCD elements). For more details see [[CoulombHadronicInterference|models of Coulomb-hadronic interference]].
