Electroweak boson production in double parton scattering

Understand

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.
