-Maldacena result to determine the strong-coupling Regge trajectory. 1

We study the interface between Regge behavior and DGLAP evolution in different non-perturbative models for the nucleon structure function. These models provide inputs for the subsequent DGLAP evolution that we calculate numerically. It turns out that the softer input gives a better fit

Received: date / Revised version: date Abstract. We study the interface between Regge behavior and DGLAP evolution in a non-perturbative model for the nucleon structure function based on a multipole pomeron exchange. This model provides the input for a subsequent DGLAP evolution that we calculate

A general nonperturbative model for the entire Compton amplitude which incorporates Bjorken scaling, gauge-invariance, and Regge behavior is presented. We show that a covariantly regularized model based on the infinite momentum frame techniques of Drell, Levy, and Yan is equivalent

for the consistency of the fixed q2 dispersion relation for vT2 (whose absorptive part vW2 is measured in inelastic electroproduction). We show that if the above conjecture is correct then there must be some energy dependence in v W2 over and above the conven-tional leading Regge form (Pomeron plus f-A2). Evidence

The physical origins and dynamical details of Regge behavior are studied by examining a general class of theories which are capable of describing the observed large momentum transfer data and extending them into the intermedi-ate t-range. The mechanism responsible for the smooth connection between

face a major drawback: the spectrum is in conflict with well-tested Regge scaling. However, while holographic duals can be modified to accomodate Regge behavior, so far it was not clear how this could be achieved in Migdal’s approach. In this paper we claim that Regge behavior cannot be achieved

The high energy behavior of the single pion photoproduction cross section has been examined, based on the Regge pole hypothesis. The possibility is pointed out that this reaction would serve for the experimental test of the Regge behavior of, particularly, the photon and p·meson. The essential

A model for a Regge trajectory compatible with the threshold behavior required by unitarity and asymptotics in agreement with analyticity constraints is given in explicit form. The model is confronted in the time-like region with widths and masses of the mesonic resonances and, in the spacelike
