Description
We aim to have a solution for the strong CP problem using softly broken Parity invariance in the context of Quark-Lepton Unified (Pati-Salam) Model where fermions acquire "see-saw" masses. The inclusion of vector-like fermions helps realize the see-saw mass mechanism. The smallness of the Physical Theta-parameter ($\bar\theta$) arises from the experimental bound of the electric dipole moment (edm) of neutron,$d_n$. In our model, $\bar \theta$ can be decoupled from neutron edm without fine-tuning and can arise only at the two-loop level.
