Abstract

This study focuses on the multiple parton scattering theory as a background for the new measurement of the inclusive cross section of the vector boson pair production at the LHC energies. The process under study is the double Drell-Yan annihilation. In this case, two quark-antiquark annihilations occur independently in one proton-proton annihilation. The final state with two pairs of leptons (electron or muon pair) is investigated while the intermedial vector boson can be both gamma and Z.
