K. Golecbiernat et J. Kwiecinski, SUBLEADING REGGEONS IN DEEP-INELASTIC DIFFRACTIVE SCATTERING AT DESY HERA, Physical review. D. Particles and fields, 55(5), 1997, pp. 3209-3211
The contribution of subleading Reggeons to the diffractive structure f
unction dF(2)(D)/dx(P)dt is estimated from soft physics data. This con
tribution leads in a natural way to the violation of the factorization
property of the diffractive structure function.
