Dip-bump structure of the elastic hadron-hadron differential cross section

For elastic hadron-hadron diffraction scattering, we examine the relation between the zeros of the scattering amplitude and the zeros of the Fourier-Bessel-transformed eikonal function from the impact-parameter space to the momentum-transfer space. Any zero of the transformed eikonal function produces a zero trajectory which becomes confluent with the one of the black-disk amplitude as the energy goes higher
