F 2 challenging DGLAP
DESY, Notkestr. 85, 22607, Hamburg, Germany
The low-x data of the structure function F 2 measured by the collaborations H1 and ZEUS are compared with the prediction of the DGLAP equations. A new method of comparing data and theory is presented. The systematic and quantitative analysis shows that the predicted 1/x behavior deviates increasingly from the observed one as x decreases below 10-3.
