This Report summarizes the results of the activities of the LHC Higgs Cross Section Working
Group in the period 2014–2016. The main goal of the working group was to present the state …

A bstract We present a practical three-step procedure of using the Standard Model effective
field theory (SM EFT) to connect ultraviolet (UV) models of new physics with weak scale …

A bstract We present results from a state-of-the-art fit of electroweak precision observables
and Higgs-boson signal-strength measurements performed using 7 and 8 TeV data from the …

A bstract We compile information from low-energy observables sensitive to flavor-conserving
4-fermion operators with two or four leptons. Our analysis includes data from e+ e− colliders …

We study the potential impact on the electroweak (EW) fits due to the tensions between the
current determinations of the hadronic vacuum polarisation (HVP) contributions to the …

A bstract We discuss electroweak precision constraints on dimension-6 operators in the
effective theory beyond the standard model. We identify the combinations of these operators …

Attempts to incorporate in a coherent picture the B-decay anomalies presumably observed
in b → cb→ c and b → sb→ s semi-leptonic decays have to face the absence of signals in …

A bstract We present the universal one-loop effective action for all operators of dimension up
to six obtained by integrating out massive, non-degenerate multiplets. Our general …

A bstract We derive model-independent constraints arising from the Z and W boson
observables on dimension six operators in the effective theory beyond the Standard Model …

We present a systematic interpretation of vector boson scattering (VBS) and diboson
measurements from the LHC in the framework of the dimension-six standard model effective …
