Abstract

The data on the diffractive deep inelastic scattering (DDIS) at HERA exhibit a strong excess, up to about 100%, above the twist-two NLO DGLAP description at low Q2Q^2 and at large energy. I show, that complementing the DGLAP fit by twist 4 and 6 components of the saturation model leads to a good description of data at low Q2Q^2 and conclude that the DDIS at HERA provides the first evidence of higher twist effects in DIS.
