Unitarization of structure functions at large 1/ x
Abstract
We discuss the effects of the schannel unitarization on the x and Q^{2} dependence of structure functions. The unitarization is implemented at the level of photoabsorption cross sections by resorting to the lightcone wave functions of virtual photons and to the diagonalization property of the scattering matrix in a basis of Fock states of the photon with fixed transverse size. The triple pomeron contribution is explicitly calculated. We find large unitarity corrections to the structure functions at x<10 ^{2}. The results are in very good agreement with the existing NMC and the preliminary HERA data.
