Conclusions

With the 1993 ZEUS data the strong rise of F₂ with decreasing x already observed in the previous year has been confirmed and is clearly visible over a large range of Q². The measured values of F₂ are in agreement with the parton distribution parametrisations from GRV, MRSA and CTEQ2D . The observed scaling violations have made it possible to derive the gluon momentum density in a new regime of x at Q² of 20 GeV². xg(x,Q²) shows a steep rise at low x when compared to the measurements from NMC at large x.
