We propose a novel kinematic method to expedite the discovery of the double Higgs (hh) production in the ℓ+ℓ−bbˉ+ET/ final state. We make full use of recently developed kinematic variables, as well as the variables Topness for the dominant background (top quark pair production) and Higgsness for the signal. We obtain a significant increase in sensitivity compared to the previous analyses which used sophisticated algorithms like boosted decision trees or neutral networks. The method can be easily generalized to resonant hh production as well as other non-resonant channels.
