Abstract

The proton structure function F₂^p(x,Q²) is described in the framework of the off-shell extention of the Regge-eikonal approach which automatically takes into account off-shell unitarity. We achieved a good quality of description for x<10^-2 and we argue that the data on F₂^p(x,Q²) measured at HERA can be fairly described with classical universal Regge trajectories. No extra, ``hard'' trajectories of high intercept are needed for that. The x-, Q²- slopes and the effective intercept are discussed as functions of Q² and x.
