Description
We develop a universal seesaw Pati-Salam model which can solve the strong CP problem via parity symmetry. Realistic fermion masses can be generated with the introduction of vector-like fermions belonging to (1,1,15) and (1,1,10) of the gauge group $SU(2)_L \times SU(2)_R \times SU(4)_c$, while keeping the Higgs sector very minimal. Loop-induced corrections to $\overline{\theta}$ are estimated and shown to be consistent with neutron electric dipole moment limits. Based on the paper ``Universal Seesaw Pati-Salam Model with P for Strong CP,'' K.S. Babu and Sumit Biswas, [arXiv:2512.25028 [hep-ph]].
