Abstract
A reanalysis of the model for the longitudinal structure function FL(x,Q2) at low x and low Q2 was undertaken, in view of the advent of the EIC. The model includes the kinematic constraint FL∼Q4 as Q2→ 0. It is based on the photon-gluon fusion mechanism suitably extrapolated to the region of low Q2. Revised model was critically updated, extended to the EIC kinematic region, and e.g. contains new parameterisations of the parton distribution functions.
