Abstract: (APS)
A strong signal for double parton scattering (DP) is observed in a 16pb−1 sample of p¯p→γ+3jets+X data from the CDF experiment at the Fermilab Tevatron. The process-independent DP parameter, σeff, is obtained without reference to theoretical calculations by comparing observed DP events to events with hard scatterings at separate p¯p collisions. The result, σeff=(14.5±1.7−2.3+1.7)mb, represents a significant improvement over previous measurements. For the first time, the Feynman x dependence of the σeff parameter is investigated, and no dependence is seen.
