Abstract
A traditional Regge model with a
Q2-independent Pomeron intercept closed (or equal) to
one is constructed in order to describe the available data on the proton
structure function. A Dipole Pomeron model which does not explicitly violate
unitarity is developed and investigated. An excellent agreement with
the 1209 data is found (
) in the whole kinematical
domain investigated by experiments.
A comparison of the model with already existing ones is
made. The x-, Q2-slopes and the effective
intercept are discussed as Q2 and x functions.
