5 May 2000 | Journal: | Nucl.Phys. B593 (2001) 336-358 | Subject: | hep-ph | Abstract: | We propose a unified approach which describes both structure functions in the small-$x$ region and diffractive production in $gamma^*p$-interactions. It is shown that the model, based on reggeon calculus and a quark-parton picture of the interaction, gives a good description of available experimental data in a broad region of $Q^2$ (including $Q^2 =0$) with a single Pomeron of intercept $alpha_P(0) = 1.2$. Predictions for very small $x$ are given and the problem of saturation of parton densities is discussed. | Source: | arXiv, hep-ph/0005049 | Services: | Forum | Review | PDF | Favorites |
