Abstract.

Using an eikonal structure for the scattering amplitude, Block and Kaidalov [1] have derived factorization theorems for nucleon-nucleon, \(\gamma p\) and \(\gamma\gamma\) scattering at high energies, using only some very general assumptions. We present here an analysis giving experimental confirmation for factorization of cross sections, nuclear slope parameters B and \(\rho\)-values (ratio of real to imaginary portion of forward scattering amplitudes), showing that:

– the three factorization theorems [1] hold,

– the additive quark model holds to \(\approx 1\%\),

– and vector dominance holds to better than \(\approx 4\%\).
