Description
We are searching the Higgs boson associated with a vector boson by using like-sign dilepton events. In these events, the most dominant backgrounds are fake events. As collecting the data, we found that the nominal W veto causes some bias in the fake ratios. Also, pT only background predictions are not sufficient because fakes depend on other variables and result in poor predictions.
In this conference, we mainly report our new fake estimations,
five-dimensional fake rate with MC-based subtraction.
