Three-gluon contribution to the neutron electric dipole moment in a model without the strong CP problem
We calculate the contribution of Weinberg's three-gluon operator to the electric dipole moment of the neutron in a left-right symmetric model which solves the strong CP problem without any Peccei-Quinn symmetry. We find that as opposed to other left-right symmetric models, the contribution from...

Summary: | We calculate the contribution of Weinberg's three-gluon operator to the electric dipole moment of the neutron in a left-right symmetric model which solves the strong
CP problem without any Peccei-Quinn symmetry. We find that as opposed to other left-right symmetric models, the contribution from the Weinberg operator is negligible compared to the experimental bound. This is shown to be a consequence of imposing the abovementioned features. |
