Contribution
It introduces one-loop Lorentz-invariant contributions to fermion electromagnetic moments from Lorentz-violating Yukawa couplings within the SME.
Findings

Discussion of Lorentz-violating contributions to electromagnetic moments
Bounds derived from experimental data
Abstract
Lorentz-violating Yukawa couplings lying within the renormalizable part of the SME generate Lorentz-invariant one-loop contributions to electromagnetic moments of fermions. These proceedings provide a discussion on such contributions and present bounds on SME coefficients from experimental data on electromagnetic moments. Constraints as restrictive as are found.
