Title:     SM EFT - Connecting UV Models to Precision Observables

Abstract: We use Standard Model effective field theory to study the sensitivities of future precision Higgs
measurements and electroweak observables in probing physics beyond the Standard Model, which
is appropriate since precision measurements are indirect probes of new physics. We restrict our
attention to a set of purely bosonic dimension-six operators, because many of the most sensitive
probes of Higgs properties involve only bosons. We describe in detail a more efficient technique,
covariant derivative expansion method, for obtaining their Wilson coefficients from UV models.
We also provide the mapping relations between the Wilson coefficients and a large set of physical
precision observables.
