Diffraction-minimum mechanism in elastic hadron scattering
Vail A. N. , Enkovskii L. L. , Struminskii B. V.
We discuss the mechanism of diffraction minimum in elastic scattering of hadrons. The dip is the result of unitary effects of the dipole-pomeron model and corresponds to absorption at small values of the impact parameter. Absorption is characterized by the constant κ = λ—1/6, where λ is determined from the total cross section and b is the slope parameter of the diffraction peak. The use of this connection as well as of the results of the quark model enables us to predict the position of the diffraction minimum in K+p scattering.
