Mixing of parton states and the real part of the amplitude of elastic scattering of high energy hadrons by nuclei
Kopeliovich B. Z., Lapidus L.I.
A mixing of parton configurations of a relativistic hadron during its transmission through a nucleus is analyzed in a two-channel model. Allowance for mixing of configurations gives a characteristic, negative, real part of the hadron-nuclear scattering amplitude, which can reach tens of percents of the imaginary part of the amplitude at energies of tens of GeV. This effect is interpreted as an example of inelastic screening in the nuclei.
