Abstract
It is shown that the CKMT model for the nucleon structure function F2 gives
a good description of the recent HERA data at low and moderate Q2.
A fit to the same data, obtained with a modified version of the model in which
a logarithmic dependence on Q2 has been included, is also presented. For moderate
values of Q2, in the
current available range of x, the first parametrization leads to a better
description of the data.
