Description
Quantum gravity impacts Standard Model particles through effective interactions generated by renormalization. These appear as SMEFT operators, which correct Standard Model dynamics at energies between the electroweak symmetry breaking scale and the Planck scale. As a step to predicting SMEFT coefficients from asymptotic safety, we investigate the flow of a representative collection of fermionic operators under gravitational fluctuations. We find a mechanism that can make these operators relevant based on symmetry arguments. This allows us to categorize SMEFT operators by their potential of providing a free parameter to the flow of the Asymptotically free Standard Model.
