Soft Color Fields in DIS at low x and low Q^2

Abstract

Two complementary approaches to DIS at low $x$ and low $Q^2$ are presented. In the first case we apply a model containig two Pomeron trajectories. In the second case we determine the gluon density in the semiclassical treatment at next-to-leading order. Both approaches rely on the concept of soft color fields.
