  We consider the differential and total cross sections for proton-proton and
proton-antiproton scattering in the Regge regime from the point of view of
string dual models of QCD. We argue that the form factor which appears in the
differential cross section is related to the matrix element of the stress
tensor between proton states and give a procedure for computing the strength of
the coupling of the Pomeron trajectory to the proton. We compute this coupling
in the Sakai-Sugimoto model and find excellent agreement with the data at large
$s$ and small $t$. The form factor can be estimated in the Skyrme model or in
AdS/QCD models and gives a stiffer form factor than the commonly used
electromagnetic form factor, in agreement with our fits to data. Our model is
also in good agreement with the measured ratio of real to imaginary parts of
the forward scattering amplitude at large $s$.
