Electroproduction structure function F2 in the low Q2, low X region

The nucleon structure function F2 in the low Q2, low x region is constructed. The analysis has been motivated by the results of the electroproduction experiments for which measurements at low values of x have been performed at the expense of lowering Q2 down to 1 GeV2 or less. Contributions from both the parton model with QCD corrections suitably extended to the low Q2 region and from the low mass vector mesons were taken into account. The former contribution results from the large Q2 structure function analysis which includes the recent F2 measurements by the New Muon Collaboration. Predictions of the model are compared with the results of the electroproduction measurements.
