Precision Cell Resampling with a Relative and Resonant Aware Metric

Abstract

We present a metric on the space of scattering events based on relative transverse momenta and with explicit sensitivity to intermediate resonances. With this new metric, negative weights in an event sample can be reduced substantially through cell resampling, while preserving the predicted properties of the resonance with high accuracy. We demonstrate the efficiency on a NLO event sample for the production of a leptonically decaying W boson together with two jets.
