Abstract
We investigate the possibility of contributions from physics beyond the
Standard Model (SM) to the Higgs couplings, in the light of the LHC data. The
work is performed within an interim framework where the magnitude of the Higgs
production and decay rates are rescaled though Higgs coupling scale factors. We
perform Bayesian parameter inference on these scale factors, concluding that
there is good compatibility with the SM. Furthermore, we carry out Bayesian
model comparison on all models where any combination of scale factors can
differ from their SM values and find that typically models with fewer free
couplings are strongly favoured. We consider the evidence that each coupling
individually equals the SM value, making the minimal assumptions on the other
couplings. Finally, we make a comparison of the SM against a single "not-SM"
model, and find that there is moderate to strong evidence for the SM.
