    9 As typical values of four-momentum transfer squared, |t|, are smaller than 10 GeV^2^ in elastic nucleon-nucleon collisions (nucleon = proton or antiproton), the influence of the weak force is negligible. 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.

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

    1111* 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]].
