# Sum rules for CP-violating operators of Weinberg type

@article{Haisch2019SumRF, title={Sum rules for CP-violating operators of Weinberg type}, author={U. Haisch and Amando Hala}, journal={Journal of High Energy Physics}, year={2019} }

Abstract
We estimate the size of the hadronic matrix elements of CP-violating three-gluon and four-gluon Weinberg operators using sum-rule techniques. In the three-gluon case, we are able to reproduce the expressions given in earlier works, while the four-gluon results obtained in this article are new. Our paper therefore represents the first systematic study of contributions to the electric dipole moment of the neutron due to CP-violating dimension-six and dimension-eight operators. We…
