Non-singlet structure functions: Combining the leading logarithms resummation at small-x with DGLAP

Abstract

The explicit expressions for the non-singlet DIS structure functions obtained at small x by resumming the most singular logarithmic contributions are discussed and compared in detail with the DGLAP evolution for different values of x and Q^2. The role played by the initial conditions for the parton densities currently used in the DGLAP analysis, on the small-$x$ behavior of the non-singlet structure functions is discussed. Explicit expressions are presented which implement the NLO DGLAP contributions with our small-x results.

Comments: The role of the standard DGLAP inputs is considered in much more detailed way than in the previous version, 8 pages, 2 figures
