Abstract

The running BFKL equation gives rise to a series of moving poles in the complex j plane. The corresponding eigenfunctions (color dipole cross sections) are oscillatory functions of the color dipole size r. The first nodes for all subleading solutions (color dipole cross sections) are clustered at r1∼0.1 fm. Therefore the processes dominated by dipole sizes rr1 are free of subleading BFKL corrections. An example of practical importance is the leptoproduction of charm. Over a wide range of Q2 the calculated F2cc(x,Q2) is exhausted by the leading BFKL pole and gives a perfect description of the experimental data.
