Abstract
In this work we obtain the DLLA limit of BFKL in the dipole picture and compare it with HERA data. We demonstrate that in leading – logarithmic – approximation, where a is fixed, a transition between the BFKL dynamics and the DLLA s limit can be obtained in the region of Q2f 150GeV2. We compare this result with the DLLA predictions obtained with as running. In this case a transition is obtained at low Q2 F5GeV2.. This demonstrates the importance of the next-to-leading order corrections to the B ...
In this work we obtain the DLLA limit of BFKL in the dipole picture and compare it with HERA data. We demonstrate that in leading – logarithmic – approximation, where a is fixed, a transition between the BFKL dynamics and the DLLA s limit can be obtained in the region of Q2f 150GeV2. We compare this result with the DLLA predictions obtained with as running. In this case a transition is obtained at low Q2 F5GeV2.. This demonstrates the importance of the next-to-leading order corrections to the BFKL dynamics. Our conclusion is that the F2 structure function is not the best observable for the determination of the dynamics, since there is great freedom in the choice of the parameters used in both BFKL and DLLA predictions. ...
