Description
Our objective is to address the strong CP problem by leveraging softly broken Parity invariance within the framework of the Quark-Lepton Unified (Pati-Salam) Model, where fermions undergo the "see-saw" mass generation mechanism. The incorporation of vector-like fermions facilitates the realization of this mechanism. The smallness of the Physical Theta-parameter ($\bar{\theta}$) is attributed to the experimental constraint on the electric dipole moment (EDM) of the neutron, $d_n$. In our model, $\bar{\theta}$ can be dissociated from the neutron EDM without requiring fine-tuning and can only arise at loop levels.
