摘要
A study of events containing at least four high transverse momentum jets and a search for double parton scattering (DPS) have been performed using data collected with the UA2 detector at the CERN ppBAR Collider (square-root s = 630 GeV). The results are in good agreement with leading order QCD calculations. A value of sigma-DPS < 0.82 nb at 95% confidence level (CL) is obtained for the DPS cross section.
