Line Operators in the Left-Right Symmetric Model

In this paper, we studied line operators in the Left-Right Symmetric Model. The gauge group of Left-Right Symmetric Electroweak Model is ${G} = SU(3) \times SU(2)_{L} \times SU(2)_{R} \times U(1)_{B - L}$. We derived the spectrum of line operators in all possible scenarios within left-right symmetric models. We then studied the $\theta$ angles in left-right symmetric model. We also discuss the effect of symmetry breaking on the spectrum of line operators and $\theta$ angles.
