A process specific methodology is defined to systematically assign theoretical uncertainties in the Standard Model Effective Field Theory when performing leading order global fits. The method outlined also minimises the computational and theoretical burden to systematically advance such analyses to dimension eight.

  1. EFT Validity and Truncation Uncertainty from few Nuisance Parameters

    hep-ph 2026-07 accept novelty 7.0 of 10

    SMEFT truncation uncertainty at O(Λ^{-4}) can be modeled by K≪N representative Wilson coefficients plus a decorrelated α=√2 PCA prior that covers full next-order effects in DY, Zh, and VBF.

  2. Beyond Scale Variations: Perturbative Theory Uncertainties from Nuisance Parameters

    hep-ph 2024-11 conditional novelty 7.0 of 10

    A framework that turns missing higher-order perturbative coefficients into fit-able theory nuisance parameters, giving correlated and statistically meaningful theory uncertainties.
