Perform a case study of the constraining power on EFT Wilson coefficients from Higgs data through STXS. Compare the sensitivity of performing a fit to the Wilson coefficients of interest via the STXS with a direct fit from LHC data and quantify any loss of information incurred.

Processes of interest:

• Associated production (VH→bb)
• Vector Boson Fusion (VBF→gamma gamma, tau tau, …)

Available UFO models:

• HEL at LO (extensive set of SILH basis operators) (link)
• HEL at NLO (small subset of SILH basis operators relevant for EW production) (link)
