Abstract
We show that analyticity and asymptotic behavior impose a severe contraint on the scale-invariant function widely suggested for the behavior of νW2(q2ν) as q2→∞. If the asymptotic behavior of the off-mass-shell Compton scattering amplitude is dominated by the usual (nonfixed) Regge trajectories, then our constraint is violated by the experimental candidates for the νW2 curve. On the other hand, the introduction of a fixed pole corresponding to the one used by Damashek and Gilman alters the constraint, which is then consistant with the 18° data.
