利用Herwig ++中的POWHEG方法，将Drell-Yan slepton对产生的次领先阶（NLO）修正与部分子簇射演化合并.在事件生成水平上的NLO校正以非全局的方式改变可观测量的形状，从而潜在地影响通过对衰变产物的关键横向动量削减和错过对事件的横向动量要求的信号事件的分数。这种效应不能通过截面的整体重新缩放来捕获，并且可能对LHC搜索的范围产生影响。
The next-to-leading order (NLO) corrections to Drell-Yan slepton pair production are merged with parton shower evolution via the POWHEG method in Herwig++. The NLO corrections at the level of event generation alter the shape of observables in a non-global way, thereby potentially affecting the fraction of signal events which pass crucial transverse momentum cuts on decay products and missing transverse momentum requirements on events. This effect is not captured by an overall rescaling of the cross section and can have repercussions on the reach of LHC searches.
