NLO-QCD event generators are expected to play a important role to extract physics signal from huge experimental data of the LHC. The cross section calculation for the hadron collider consists of two parts, one is the fixed order matrix element and the other is the soft/collinear resummantion part (PDF/parton-shower). If these two parts are simply connected, double counting of the soft/collinear parton-emission effect from the matrix element and the PDF/parton-shower cannet be avoidable. We proposed a new method to construct NLO event-generators without any double countings (leading log subtraction method).
