Abstract
A model for the longitudinal structure function FL in the region of low x and low Q2 is discussed. It is constructed using the kT factorization theorem and a photon-gluon fusion mechanism suitably extrapolated to the region of low Q2. A phenomenological model for higher twist is presented, which is based on the assumption that the contribution of quarks having limited transverse momenta is dominated by the soft pomeron exchange mechanism.
