Up: An update of the
The update results on obtained by this analysis are
consistent with the those presented in 1996 even if they are
systematically lower due to the overestimation of the
They are in agreement with official ZEUS results, except for few bins
in the highest region, although the discrepancy is within the
After all cross checks the only difference between this and the other
analysis remains that due to the different unfolding and uncertainty
The agreement can be also seen from the comparison
(figure 5) with the NO QCD fit,
made using the the published data.
In some bins the agreement to the fit is even
better than that of the published data.
Finally, it is worth noticing that this analysis allows to evaluate
the covariance matrix of the data points, which it is
not trivial (see table 2) and it can be of crucial
importance to extract precise QCD informations from the data.
