The $ggh$ variations

Understand

We examine how sub-leading results in the operator and loop expansion for $\sigma(\mathcal{G} \mathcal{G} \rightarrow h)$ in the Standard Model Effective Field Theory (SMEFT) inform theoretical error estimates when studying this production channel in global SMEFT studies.

• We also discuss the relationship between geometric SMEFT results and the $\kappa$ formalism.
