Abstract.

A comparative phenomenological analysis of Regge models with and without a hard pomeron component is performed using a common set of recently updated data. It is shown that the data at small x do not indicate explicitly the presence of the hard pomeron. Moreover, the models with two soft-pomeron components (simple and double poles in the angular momentum plane) with trajectories having intercept equal to one lead to the best description of the data not only at W >3 GeV and at small x but also at all \(x\leq 0.75\) and \(Q^2\leq 30000\) GeV\(^2\).
