N2 - We determine the fraction of events with double parton (DP) scattering in a single pp¯ collision at s√=1.96 TeV in samples of γ+3 jet and γ+b/c jet+2 jet events collected with the D0 detector and corresponding to an integrated luminosity of about 8.7 fb−1. The DP fractions and effective cross sections (σeff) are measured for both event samples using the same kinematic selections. The measured DP fractions range from 0.21 to 0.17, with effective cross sections in the γ+3 jet and γ+b/cjet+2 jet samples of σincleff=12.7±0.2(stat)±1.3(syst) mb and σHFeff=14.6±0.6(stat)±3.2(syst) mb, respectively.
