Precocious asymptopia for charm from the running BFKL

Abstract

The running BFKL equation gives rise to a series of moving poles in the complex j-plane. Corresponding eigenfunctions (color dipole cross sections) are the oscillating functions of the color dipole size rr. The first nodes for all sub-leading solutions (color dipole cross sections) accumulate at r10.1fmr_1\sim 0.1 fm. Therefore the processes dominated by the dipole sizes rr1r\sim r_1 are free of sub-leading BFKL corrections. A practically important example - the leptoproduction of charm. In a wide range of Q2Q^2 the calculated F2cc(x,Q2)F_2^{cc}(x,Q^2) is exhausted by the leading BFKL pole and gives a perfect description of the experimental data.
