Impact of SMEFT renormalisation group running on Higgs production at the LHC
arxiv(2024)
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, tt̅H 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.
