SMEFT at NNLO+PS: Vh production

Journal of High Energy Physics
Abstract In the context of the Standard Model effective field theory (SMEFT) the next-to-next-to-leading (NNLO) QCD corrections to the Higgsstrahlungs (Vh) processes in hadronic collisions are calculated and matched to a parton shower (PS).

Mapping the SMEFT to discoverable models

Journal of High Energy Physics, 2022
The matching of specific new physics scenarios onto the SMEFT framework is a well-understood procedure. The inverse problem, the matching of the SMEFT to UV scenarios, is more difficult and requires the development of new methods to perform a systematic ...

A global analysis of axion-like particle interactions using SMEFT fits

Journal of High Energy Physics, 2023
In the presence of axions or axion-like particles (ALPs) that couple to the Standard Model via dimension-five interactions, dimension-six SMEFT interactions are generated via renormalization-group evolution.

Renormalisation group effects on SMEFT interpretations of LHC data

Journal of High Energy Physics, 2023
We explore the impact of Renormalisation Group (RG) effects in the Standard Model Effective Field Theory (SMEFT) interpretations of LHC measurements.

Uniting low-energy semileptonic and hadronic anomalies within SMEFT

Journal of High Energy Physics
Two categories of four-fermion SMEFT operators are semileptonic (two quarks and two leptons) and hadronic (four quarks). At tree level, an operator of a given category contributes only to processes of the same category.

Renormalisation group evolution effects on global SMEFT analyses

Journal of High Energy Physics
Global analyses in the Standard Model Effective Field Theory (SMEFT) framework serve as a tool to probe potential directions of new physics. To break degeneracies between the Wilson coefficients of the SMEFT, it is essential to combine observables from ...

The importance of flavor in SMEFT Electroweak Precision Fits

Journal of High Energy Physics, 2023
Effective field theory tools are essential for exploring non-Standard Model physics at the LHC in the absence of the discovery of new light particles.

Dimension-8 SMEFT matching conditions for the low-energy effective field theory

Journal of High Energy Physics, 2023
In particle physics, the modern view is to categorize things in terms of effective field theories (EFTs). Above the weak scale, we have the SMEFT, formed when the heavy new physics (NP) is integrated out, and for which the Standard Model (SM) is the ...
