Implications of unitarity and charge breaking minima in a left-right symmetric model

Abstract

We examine the usefulness of the unitarity conditions in a left-right symmetric model which can translate into giving a stronger constraint on the model parameters together with the criteria derived from vacuum stability and perturbativity. In this light, we demonstrate the bounds on the masses of the physical scalars present in the model and find the scenario where multiple scalar modes are in the reach of the Large Hadron Collider. We also analyze the additional conditions that can come from charge breaking minima in this context.
