A study of processes with double parton interactions (DPI) in pp̄ collisions collected by DØ detector at the Tevatron collider at √s = 1.96 TeV is presented. The study includes measurements of DPI event fraction and the effective cross section, a process-independent parameter related to the effective interaction region inside a hadron. The measurements are done using processes with photon and hadronic jets in different parton-parton scatterings: photon+jet + dijet, photon+b/c + dijet and diphoton + dijet. The measured effective cross section is applied in order to estimate background from DPI processes to WH production at the Tevatron energy.
