THE CKMT Model and the Theoretical Description of the Caldwell-plot
Abstract
The CKMT model for the nucleon structure function F2 is in good agreement with the HERA data at low and moderate Q2. The 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 discussed. Finally, we show how the parametrization of the CKMT model for the nucleon structure function F2 describes the HERA data when presented in the Caldwell-plot as the behavior of the logarithmic slopes of F2 vs x and Q2.
