Abstract
Measurements of g(1) at low x and low Q(2) are expected to provide a sensit ive probe of the transition from Regge to perturbative QCD dynamics, offeri ng a new testing ground for models of small x physics. We discuss the poten tial of polarized ep colliders (Polarized HERA and eRHIC) to investigate th is physics - varying Q(2) between 0.01 and 1 GeV2 - and to constrain the hi gh-energy part of the Drell-Hearn-Gerasimov sum-rule for polarized photopro duction.
