A method is suggested to combine tree level QCD matrix elements for the production of multi jet final states and the parton shower in hadronic interactions. The method follows closely an algorithm developed recently for the case of e+e− annihilations \cite{Catani:2001cc}.

Combining higher-order resummation with multiple NLO calculations and parton showers in GENEVA (2012, methodology): “This directly corresponds to the CKKW-L procedure [1, 2, 36, 37], which multiplies the tree-level matrix elements with the shower Sudakov factors.”
General-purpose event generators for LHC physics (2011, background): “(18), and it can be shown that this is related to the Sudakov form factor needed in the merging by a simple ratio of parton density function[82, 83] (see also [3]), such that”
