摘要：

A new solution is found for the Dyson-Schwinger equation for the gluon propagator in the axial gauge. Unlike previously found ones this propagator does not display a 1/k4 pole as k --> 0 but has a very soft singularity in this region. Thus it represents a gluon which is not confining but rather confined since in configuration space the propagator vanishes for large impact parameters. This solution is relevant for processes in which soft gluons are exchanged, such as physics at low x or equivalently the construction of the QCD pomeron. Some of the phenomenological consequences are discussed.
