Feasibility of direct study of the character of strong interactions at short distances in experiments on e collisions. Role of quasilocal terms
Ginzburg I.F.
The amplitude, which is determined only by the character of the interaction at short distances, can be measured directly in experiments on deep inelastic e e scattering (virtual forward yy scattering). The form of the amplitude depends essentially on the character of the quasilocal (contact) terms. The possible form of the amplitude is discussed for models in which the strong interaction is turned off at short distances, and in a model in which this interaction is scale-invariant.
