Precision Cell Resampling with a Relative and Resonant Aware Metric

Andreas Maier, Ella Cole, Jeppe R. Andersen

A metric using relative transverse momenta and resonance sensitivity lets cell resampling cut negative weights while keeping resonance shapes intact.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

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.

C2weakest assumption

That the proposed metric, when used for cell resampling, does not introduce biases that distort the resonance properties or other observables beyond what is claimed, even though the metric definition itself involves specific choices for relative momenta and resonance sensitivity.

C3one line summary

A resonance-sensitive metric using relative transverse momenta allows cell resampling to reduce negative weights in NLO W+2jets samples while preserving resonance predictions with high accuracy.
