Impact of SMEFT renormalisation group running on Higgs production at the LHC
abstract
We study the effects of the one-loop renormalisation group running/mixing of the Wilson coefficients in the standard model effective field theory on the predictions for $Hj$, $t\bar tH$ and $HH$ production at the LHC. We focus on a subset of operators closed under QCD corrections and explore the differences between employing a fixed or dynamical scale on the SMEFT predictions for key observables such as the Higgs transverse momentum and the Higgs pair invariant mass. We then study the impact of consistently taking into account renormalisation group effects on the constraints that can be obtained on the Wilson coefficients through current and future measurements at the LHC.

The effect of the two-loop SMEFT RGEs at future colliders
Two-loop SMEFT RGEs induce non-negligible effects on the evolution of Wilson coefficients, leading to percent-level shifts in projected sensitivities for four-quark, top Yukawa, and Higgs-gluon operators in collider fits.
