  We study the $W^+W^-$ and $Z^0Z^0$ electroweak boson production in double
parton scattering using QCD evolution equations for double parton
distributions. In particular, we analyze the impact of splitting terms in the
evolution equations on the double parton scattering cross sections. Unlike the
standard terms, the splitting terms are not suppressed for large values of the
relative momentum of two partons in the double parton scattering. Thus, they
play an important role which we discuss in detail for the single splitting
contribution to the cross sections under the study.
