INCLUSIVE LOW Q² MEASUREMENTS AT HERA

Inclusive ep scattering measurements at low virtualities of the exchanged boson, Q², allow precision tests of perturbative QCD at high gluon densities, as well as studies of the transition from the perturbative to non-perturbative QCD domain. Measurements in the transition region require special experimental approaches due to the limited detector acceptance. The current status and results of low Q² measurements at HERA are summarised.
