| abstract in english: | An analysis of twist composition of Balitsky–Kovchegov (BK) amplitude is performed in the double logarithmic limit. In this limit, the BK evolution of color dipole–proton scattering is equivalent to BFKL evolution which follows from vanishing of the Bartels vertex in the collinear limit. We perform twist decomposition of the BFKL/BK amplitude for proton structure functions and find compact analytic expressions that provide accurate approximations for higher twist amplitudes. The BFKL/BK higher twist amplitudes are much smaller than those following from eikonal saturation models. |
