摘要: Abstract The cross section for the photoproduction of events containing three jets with a three-jet invariant mass M3J>50 GeV has been measured ZEUS detector at HERA. angular distributions are inconsistent uniform population available phase space but well described by parton shower models and O (αα s 2 ) pQCD calculations. Comparisons model indicate strong contribution from initial state radiation as sensitivity to effects colour coherence.
