Discovery of the Higgs boson decay to dimuon is anticipated soon based on the current evidence. Precise categorization of events without affecting the invariant mass shape is crucial in the analysis. Decorrelation of the invariant mass and the output of discriminators (the score of discriminators) is essential for consistent and precise analysis. In this paper, we use distance correlation as an additional loss function to achieve the decorrelation for discriminators and examine various analysis methods. The significance of the Higgs to dimuon signal from gluon fusion is considerably improved by including jet substructure variables.
