We extend the universal one-loop effective action (UOLEA) by operators which translate between dimensional reduction (DRED) and dimensional regularization (DREG). These regularization scheme translating operators allow for an application of the UOLEA to supersymmetric high-scale models matched to non-supersymmetric effective theories. The operators are presented in a generic, model independent form, suitable for implementation into generic spectrum generators.

  1. A Guide to Functional Methods Beyond One-Loop Order

    hep-ph 2024-12 conditional novelty 7.0 of 10

    Functional methods are generalized to two-loop EFT matching and running with manifest gauge covariance, and the hard-region matching formula is proven to all loop orders.

  2. Completing the scalar and fermionic Universal One-Loop Effective Action

    hep-ph 2019-08 conditional novelty 7.0 of 10

    A complete set of generic one-loop Wilson coefficients for scalar and fermion loops up to dimension six, excluding open covariant derivatives, is derived and validated on MSSM examples.

  3. Effective field theory and scalar extensions of the top quark sector

    hep-ph 2019-08 accept novelty 6.0 of 10

    For a heavy scalar coupled to top quarks, only an NLO-matched effective field theory reproduces the full model across the LHC energy range, while a leading-order fit overestimates the high-mass tail and LHC constraints.
