We propose a novel mechanism for the cosmological production of keV - GeV mass dark matter that interacts with the Standard Model through a small effective magnetic dipole moment. Such an interaction can be radiatively generated if dark matter couples to heavier charged particles. Previous studies have focused on the case where these charged states are much heavier than the reheat temperature,...

41. Spontaneous CP violation in an axion model with seesaw mechanism

Prof. Sin Kyu Kang (Seoul National University of Science and Technology)

We study a sequestered realization of spontaneous CP violation in an extension of the DFSZ axion framework.

CP is imposed at the Lagrangian level, so that all couplings and mass parameters are real.

The only physical source of CP violation arises from a PQ-invariant relative alignment of the singlet vacuum expectation values.

Since this CP-odd vacuum parameter is orthogonal to the...
