CCFM prediction for F_2 and forward jets at HERA

Abstract

Predictions of the CCFM evolution equation for F_2 and forward jets at HERA energies are obtained from a modified version of the Monte Carlo program SMALLX. The treatment of the non-Sudakov form factor ${\Delta }_{ns}$ is discussed as well as the effect of the so called "consistency constraint". For the first time a good description of F_2 and the forward jet data is obtained from the CCFM equation.
