We point out that, although SMEFT is constructed to be model-independent, this holds only if complete sets of operators are used. SMEFT analyses that focus on subsets of operators are only semi-model-independent. They probe classes of ultraviolet models, opening a window to the underlying new physics.

Energy-enhanced dimension eight SMEFT effects in VBF Higgs production
Journal of High Energy PhysicsWe study Higgs boson production via vector boson fusion at the LHC, focusing on the process pp → H + jj and capturing the leading energy-enhanced contributions within the Standard Model Effective Field Theory (SMEFT) up to order 1/Λ4.

Walls, bubbles and doom — the cosmology of HEFT
Journal of High Energy PhysicsAs experiment charts new territory at the electroweak scale, the enterprise to characterise all possible theories becomes all the more necessary. In the absence of new particles, this ambitious enterprise is attainable and has led to the Higgs Effective ...

RGE effects on new physics searches via gravitational waves
Journal of High Energy PhysicsGravitational wave (GW) observations offer a promising probe of new physics associated with a first-order electroweak phase transition. Precision studies of the Higgs potential, including Fisher matrix analyses, have been extensively conducted in this ...

Matching for FCNC effects in the flavour-symmetric SMEFT
Journal of High Energy Physics, 2019 We calculate the complete tree and one-loop matching of the dimension-six Standard Model Effective Field Theory (SMEFT) with unbroken U(3)5 flavour symmetry to the operators of the Weak Effective Theory (WET) which are responsible for flavour changing ...

Triboson production in the SMEFT
Journal of High Energy PhysicsAbstract We study the production of three electroweak gauge bosons at the LHC, in the effective field theory of the standard model, at dimension six and next-to-leading order in QCD. We present results for inclusive cross-sections and differential distributions, finding that these QCD corrections are large, often vary across the ...
